Before your mind starts wandering around in effort to find a reasonable answer to the question in our title, let’s get it straight right away and tell you that it’s only a joke from the popular TV show “How I Met Your Mother”. In the 20th episode named “Mosbius Designs” of season 4, Barney Stinson, portrayed by Neil Patrick Harris, told one of the dirtiest jokes in the history of TV shows and movies. He told the joke to Lily, who found the joke so offensive that she actually refused to hang out with the gang for 4 weeks.
The reason for the show producers of “How I Met Your Mother” have decided to make Barney tell such a dirty and offensive joke to Lily (Alyson Hannigan) is because Alyson was pregnant in real life and needed to get away from the show for a while. Due to her maternity leave, the season finale was shot in advance as Lily made her return to the gang in episode 24. But since the audience did only get to hear the setup of joke (what’s the difference between peanut butter and jam) on her way towards the boys, the Internet went crazy about finding the punchline. Even after 9 years, people who are yet watching HIMYM are looking for an explanation of the joke.
How I Met Your Mother: What’s the Difference Between Peanut Butter and Jam?
After Ted and Marshall refuse to tell Lily the joke they were laughing about, explaining themselves that it is boy-funny, Barney whispers the punchline to her, but the narrator Future Ted does not tell it to the audience. Although she asked for it, Lily found the joke so dirty that she walked off and didn’t speak to the guys for a month. In real life, that’s when she gave birth to Satyana. Instead of ignoring the elephant in the room, the directors of “How I Met Your Mother” joked about the pregnancies of Robin and Lily, which was a refreshing decision compared to other shows.
But what was the joke really about? Was it really that offensive and dirty? Or it were Lily’s hormones that made her overreact? Well actually, the show did never hint us any answer, but thanks to the brilliant guys on the Internet, we’ve found an explanation that we certainly regret Googling. As it turns out, the original joke is: What’s the difference between jam and marmalade? And the answer: You can’t marmalade your d**k up a girl’s ass. Barney’s joke is almost the same, except that he used peanut butter instead of marmalade.

The Punchline: You can’t peanut butter your d**k up a girl’s ass.
In the footage you can see Barney mouthing the words “peanut butter”, while the rest of the joke as well as the punchline are impossible to read from his mouth. Some hard-core fans of the show even believe that he told a variation of the what’s the difference between peanut butter and jam joke that was even more rude, more offensive and dirtier than the punchline we know of. What sort of a punchline could have Barney possibly came up with to a joke so simple that made Lily avoid the gang for 4 straight weeks?
If you relate Lily’s reaction to this answer of the joke that Future Ted narrates, it makes a perfect sense that Barney actually told her this joke. While many may argue that this joke is not the dirtiest or the most offensive one, it certainly is one that every fan of HIMYM knows and laughs on every time someone tell it.
