OH, THE highs and lows of social media.

Right after Amy Schumer was applauded for shutting down a teen film critic for a sexist tweet he made at her expense, she’s now being accused of stealing jokes by comedians on the social platform.

In a now-deleted Twitter conversation over the weekend, three female comedians — Wendy Liebman, Tammy Pescatelli and Kathleen Madigan — all made mention of particular bits in Schumer’s stand-up and TV show that are strangely similar to their own material.

Now, it may just seem like sour grapes, but Pescatelli did note that Schumer was a supporting act to the comedians over the years as she rose through the ranks on the comedy scene.

While most of the tweets are now deleted (not before they were captured by users and posted on several forums), it all started when Liebman expressed frustration at seeing one of her jokes in Amy Schumer’s HBO special Amy Schumer: Live at the Apollo.

“Between Amy Schumer doing 1 of my best jokes on her HBO special and this meme of my joke, I’m done with social media,” she wrote.

It’s suggested the joke Liebman’s referring to is one she made regularly in her routines in the 1990s. “Maybe I’m old fashioned but I like it when the guy pays ...” she’d say before pausing, “... for sex”.

And Schumer indeed makes a similar throwaway line in her HBO special: “I am a good person, I swear to you; I’m very old school. I think the guy should always pay on the first date for sex.”

Chuck Martin, a comedian and writer who’s worked on Arrested Development, responded, suggesting Liebman talk to fellow comedian Kathleen Madigan, who’s experienced a similar issue with Schumer. Comedian Tammy Pescatelli also jumped in.

“What has always been amazing to me is that she purports to be a feminist and yet only steals from other female comedians,” Pescatelli wrote in now-deleted tweets. “If we call her on it we are ‘jealous’ or career shamed. Be successful. WE want you to do well, just do it (with) your own material. BTW she blocked me.”

Pescatelli referred to a clip from Madigan’s 2006 Comedy Central special and compared it to a skit featured in the first season of Amy Schumer’s show Inside Amy Schumer.

“I get why poor people are fat,” Madigan’s joke begins. “But Oprah, you’re a billionaire. You have enough money to pay a man to stand there and literally slap sh*t out of your hand before you put it in your mouth. You could hire a fulltime food slapper.

“You’re so rich you could pay someone to exercise you. You could just lay there like a baby with cerebral palsy and have people move your legs.”

The Schumer skit in question, entitled “Slap Chef”, is a spoof commercial for a new dieting service. A voiceover details how customers can pay a chef to make them a delicious meal and then slap it out of their hands before they eat it. In the skit, another service called “Sleep Gym” is advertised, where clients are induced into a coma and trainers move their body for them while they’re unconscious.

“So many more but nobody listens ... at least Cosby knocked his victims out b4 he raped them,” Pescatelli added.

Pescatelli also tweeted a clip from her own 2006 Comedy Central routine where she jokes about the way men dress and compared it to a joke that’s used in the promo trailer for Schumer’s 2015 film Trainwreck.

“As a woman, I will admit, women dress for other women,” Pescatelli begins in her 2006 comedy special. “That’s why men, if we love you, we dress you for other women too — that’s why we dress you stupid. Because we want another woman to look at you and go, ‘He’s cute but I can’t fix all of this’. Who do you think invented the Hawaiian shirt?”

In Trainwreck, Schumer is talking to her on-screen sister about her brother-in-law when she makes a crack at his outfit: “Ooh, I like Tom’s sweater. Does he teach computer in a church basement? You dress him like that so nobody else wants to have sex with him? That’s cool.”

When some Twitter users began to accuse the comedians of being jealous of Schumer’s success, they were quick to point out they weren’t trying to create a “beef” but just stating “facts”.

Amy Schumer has defended herself on Twitter and claims that she “would never steal a joke”.

On my life, I have never and would never steal a joke. — Amy Schumer (@amyschumer) January 20, 2016

By the way. it’s not the first time she’s been accused of ripping off a joke.

Last year, a joke she made about made-up sex positions was compared to a similar routine by late comedian Patrice O’Neal.
