Joe Biden says Donald Trump needs to “grow up” now that he’ll be president.

The lame-duck vice president offered the advice on PBS NewsHour in response to a question about Trump’s Twitter habits.

Judy Woodruff asked Biden about Trump’s tweet where he called Senate Minority Leader Chuck Schumer “head clown” after Schumer vowed to stop Trump from repealing Obamacare. Schumer also threatened to block all of Trump’s Supreme Court nominees.

Meryl Streep just got checkmated by a guy with one hand – nobody can beat his response!

The Democrats, lead by head clown Chuck Schumer, know how bad ObamaCare is and what a mess they are in. Instead of working to fix it, they.. — Donald J. Trump (@realDonaldTrump) January 5, 2017

…do the typical political thing and BLAME. The fact is ObamaCare was a lie from the beginning."Keep you doctor, keep your plan!" It is…. — Donald J. Trump (@realDonaldTrump) January 5, 2017

…time for Republicans & Democrats to get together and come up with a healthcare plan that really works – much less expensive & FAR BETTER! — Donald J. Trump (@realDonaldTrump) January 5, 2017

Biden said Trump needs to behave more responsibly going forward.

“Grow up, Donald, grow up,” Biden said. “Time to be an adult, you’re president.”

The two-time failed presidential candidate added: “Show us what you have. You’re going to propose legislation. We’re going to get to debate it. Let the public decide. Let them vote in Congress. Let’s see what happens.”

Clueless Joe doesn’t seem to realize that is exactly what Trump is asking Congress to do: Wait and see how he does, instead of vowing to obstruct him BEFORE he takes office, the way Schumer and Congresswoman Maxine Waters have.

Waters refuses to work with Trump and won’t even meet with him for the next 4 to 8 years. “I’m going to fight him every step of the way,” Waters promised.

Meanwhile, Twitter reacted to Joe Biden’s comment by saying he needs to behave more like a grown-up himself, instead of like the “creepy uncle” you avoid at family gatherings.

Others pointed out that Biden’s inappropriate displays of affection span all generations.

When it comes to awkward kisses, even men are not immune, because Joe’s an equal-opportunity offender.

Then, there are the dumb things “grown-up” Biden has said over the years.

"You got the first mainstream African-American who is articulate, bright, clean, and a nice-looking guy. I mean, that's a storybook, man." — Shit Joe Biden says (@Why_I_hate_Life) October 14, 2013

Remember when Joe said all Indians work at 7-11 or Dunkin’ Donuts?

That time when Joe said the (still-alive) mother of visiting Irish Prime Minister Brian Cowen was dead …

Then there was the time when “grown-up” Joe identified the guy with the nuclear codes at a Hillary Clinton rally.

At a Clinton rally in August, VP Biden said, "There's a guy that follows me—right back here—has the nuclear codes." This is not a secret. /7 — Stephen Schwartz (@AtomicAnalyst) December 24, 2016

And don’t forget the time he asked Sen. Chuck Graham, who’s paralyzed from the waist down, to stand up to be recognized by the crowd at a rally.
