Mr. Bean

Just to clarify, both are technically correct. However, it would be wrong to say "You speak French good" because good would be describing speak. Speak is a verb, obviously, and good is an adjective, not an adverb. In the statement "You speak very good French", good is describing the word French, which is being used as a noun. Thus, it is perfectly acceptable. :) I hope I don't sound rude; I just wanted to clear things up.

well alrighty then! :)

Umm, I think the other comment was just trying to clarify that in the movie, the attendant says you speak French very well

In the movie she says "You speak very good French."

He does there

Aaaaaaand the joke's dead.
