Callum 

Slightly, strange (OK, not slightly, very strange) and not exactly the brightest. Loves nothing more than annoying all his "friends" very much. However, although he's annoying, he's really good at sports including tennis, badminton and cross-country. And is OK company, some of the time...

That guy's not very smart, bet he's a Callum.
