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. ^____^

I keep track of every "Justin" and "Sunshine" that comes out of Brian's mouth. It's an obsession.

I thought he said Justin fairly regularly? Guess not.
How rare is it?

He says it when he's talking about him to someone else (but even then...not all that often) but he very rarely says it TO Justin. And it's especially obvious since Justin "Brian Brian Brians" all the time.

He usually only says Justin's name when he's worried about him, seems like.

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
