Que tendrá que ver la velocidad con el tocino
 

EnGLISH?

¿Qué quiere decir en español? Bueno, quizás sería "What's that got to do with the price of fish", pero es pura adivinanza.

se usa cuando dos cosas no tienen nada que ver, no tienen comparación. Y se usa en cualquier contexto.

What's that got/have to do with ...
... the price of fish? (Britain and Australia)
... the price of tea in China?
... the price of rice in China?
... the price of eggs?

My favorite thing to say to someone who says something off-topic is:
There are no bones in ice cream.

This is usually said with quite a bit of disbelief, as if you just heard the other person state that there are bones in ice cream.
