Is it correct grammar to say you and bob?

"You and Bob" is grammatically correct, but it depends on the context.

Here's why:

* Subject: If "you and Bob" are the subject of a sentence, it's correct:

* "You and Bob are going to the movies."

* Object: If "you and Bob" are the object of a sentence or preposition, it's also correct:

* "I gave the tickets to you and Bob."

* Informal: In informal situations, you might hear "Bob and you" which is still grammatically correct but might sound a bit odd in a formal setting.
