If you're a burrito and you know it...

In Spanish class the other day, we were reviewing something that we have learned at least three times already. This happens at the beginning of every year, but still gets a bit annoying. It's the kind of thing where it seems as if you've already done all the examples before already done all the examples before... woah, déjà vu. That sort of thing. Anyway, Student A tried to say "Yo estoy aburrido," or "I am bored," but accidentally said "Yo es burrtio." I is burrito. He asked me not to use his name... I wonder why...?
