Orchestra Christmas Puns

I told her I will Czech them out once December comes

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
