Marketers are trained to think big. Cause disruption. Change the game. Make an impression. Shake shit up.

Of course, they’re not always taught how to think things all the way through.

In an Ask Reddit discussion, redditor ConsciousMinded wondered, “Which publicity stunt backfired the worst?”

Redditors recalled some of the most epic promotion blunders in history, starting with a tale of an Atlanta radio station that decided to celebrate Thanksgiving by throwing live turkeys into a crowd—only to realize that the turkeys couldn’t fly. (The real-life incident—which ended with splatters of bird carnage—inspired a hilarious episode of the late-1970s sitcom WKRP In Cincinnati.)

Here are some of the top disasters.

When Snapple tried to make the world’s largest popsicle

Lol, In 2005 Snapple tried to set a world record by making a giant popsicle…it melted and flooded union square pic.twitter.com/XcktJrV7t6 — Mistertitanic44 (@Mistertitanic33) April 4, 2015

Ken Giddon, owner of the clothing store Rothman’s, described the scene like this in Newsday: “A small wave of slush began moving across 17th Street … It wasn’t a bad smell. But the people stepping in it were not pleased. People were pretty bummed out with what was going on with their shoes.”

Lesson learned: Ice melts.

When American Airlines offered lifetime, fly-anywhere, First Class travel passes for $250K

One redditor remembers the passes fondly.

Lesson learned: When you offer an all-you-can-eat buffet, you’ve gotta prepare for the Homer Simpsons.

When Mountain Dew Let The Internet Name Its New Drink

Lesson learned: The Internet be the Internet. More cases in point: when online voters chose a school for deaf students as a concert location for Taylor Swift, when they selected this computer science grad as the winner of Next’s model competition and most recently, when they overwhelmingly favored Boaty McBoatface as the name for a new research ship in the UK. The people have spoken!

When The NYPD Asked People To Tweet Photos of Themselves With Officers

The responses weren’t what they were expecting.

Lesson learned: Be careful what you ask for.

When the Cleveland Indians hosted 10 Cent Beer Night

There was streaking, exploding firecrackers and people literally stealing bases. Here’s Bob Golic’s recount of the 1974 incident.

Lesson learned: People like cheap alcohol.

When The Fine Bros Announced React World

YouTubers Benny and Rafi Fine, known for their “reaction videos” (for example, Elders React to Twerking, Cats React To Viral Videos and Teens React To 90s Internet), set off an Internet revolt that led them to lose roughly 7,500 YouTube subscribers an hour. It happened when the Fine Bros announced the launch of React World, a franchising program that would grant content creators licenses to make their own renditions of the shows. The offense? They registered a trademark for the word “react,” which many saw as greedy, underhanded way of trying to monopolize the market. They later pulled their trademark application.

Lesson learned: Don’t mess with the little guys.
