Did Brian ever actually drink guava juice in the canon?

I have been reading a lot of QaF fic recently, and it is constantly mentioned that Brian likes to drink guava juice. 
I have no memory of this ever being mentioned in the show. Is this just a product of the fannon? Was it mentioned somewhere in the show - and I just don't remember? 

I hope that someone can help me figure this out. ^____^

Interesting observation.
I will have to watch more carefully next time I watch.
And yes, Justin does say Brian a lot - and a lot of other things that Brian refuses to say.... :D
