Contra Puns

Because of his contra band...

contra-band

Yeah, he's a walking Contra-diction.

Alternative for the logic nerds:

Bob is always honest, and he says he doesn't like shoot 'em ups. His identical twin Joe says he loves shoot 'em ups. How do we know Joe is honest? Because if something is true, then so is its Contra-positive.

important, my family speaks Spanish

After my school's Christmas concert, I went out to eat with my family. They were asking me about some people who were announced for having made it into the All-State Band and Orchestra, one of which was a string bass player (contrabajo in Spanish).

I told them: "Si... Ella toca contrabajo. (Yes... She plays string bass.)"

And my dad replies: "¿Pues si toca con trabajo, porque la aceptaron? (Well if she plays with difficulty, why did they accept her?)"

TL;DR: Contrabajo = string bass, con trabajo = with difficulty

Because he was all about the con ami code
