Shelby Name Puns

So yesterday I went to the movie theater with my dad and we saw Need For Speed. In the movie they talk a little bit about Caroll Shelby, a famous performance cars designer. After the movie we talked a bit about him and he told me :

-I think Caroll Shelby designed my car.

I told him : I'm pretty sure he did not, you have a shitty little car but why do you think so?

He said : Son, it's obvious Mr Caroll named the Carolla after himself.
