te see Rigby watching te sleep. What would te do?

Tell him that Edward Cullen for Twilight is not a good role model.

I'd say "Rigby! What are te looking? get outta here before I call the cops for breaking into my house!"

'Holy! Crap, Rigby, I thought te were SlenderMan!' is what I'd say C:

I wouldn't do a thing, because if I saw a 3 feet tall cartoon character watching me sleep, I would assume that I am completely stoned, and in order not to freakout I would just enjoy seeing one of my preferito characters

I'd look at him, get out of letto and ask him where the other characters are. After he tells me, I'll slap him and call him a perv, as I normally sleep naked ( AND without a blanket)
