There is a type of pepper we like to call Bell Pepper. The joke is untranslatable in english.
In spanish the joke would be: Se llama chile campana porque pica cuando entra y repica cuando sale.
The sound a bell makes is called "repicar" in spanish, but it is also a play on "pica" which means itches. Untranslatable, but still. That thing stings like a motherfucker. Delicious though.
