Day -27: A Joke

This joke is only funny if you know a little Spanish. Plus, it works much, much better orally than on paper. But anyway ... I'll tell it first and then explain after.

It was time for lunch and my students were talking about beans for some reason. "They give you gas!" one boy said.

"Yeah," another boy added, switching to Spanish. "Mi papá dice que los frijoles tienen la vitamina P2."

Explanation:
The boy said, "My dad said beans have vitamin P2."
The letter "p" in Spanish is pronounced like the word "pay" in English.
The number 2 in Spanish is "dos," pronounced with a long-o sound.
The word for farts in Spanish is "pedos" - pronounced "pay-dos."
P2=pedos

I was excited because I hardly ever get jokes in Spanish right away, but I got this one!

Maybe this doesn't make sense online ...
