Sister's Pseudo-Boyfriend comes over too much

Bad jokes, something gross, "Where did you buy those shoes? (or anything he's wearing) They're kind of ugly." Bathroom stuff, or just geeky stuff that will get them bored but they will feel so akward that won't be able to ask you to shut up, ask him about his ex girlfriends, I don't know...try until something works...

Or tell him "I have problems sleeping but what I do is:

Eat a lot of cheese during the day, and before you go to bed take a massively painful shi't. The screams and moans of pain combined with the constant pushing of the muscles in your stomach will make you tired enough to sleep at night.
