Since when do tunafish eat mayonaise?

Tunas dont eat mayo.  Unless I am totally wrong.  No one should eat mayo though, it's gross.  Sorry if you like mayo.  But hey, yosh is japanese slang for awesome, so like, instead of saying awesome or whatever, we should just say yosh, and that'll totally become a thing.  me and maggie are already saying yosh all the time, so do it.
