What makes you think I don't take myself seriously? I'm serious, if I wasn't then I wouldn't be in sixth year right now, I'd be in fourth with everyone else by age.

What kind of experience?

Hiding it all over the tower is getting too easy for him to find, but if he thinks it's out side of the tower, he'll use his deductions to find it. You can let on that I had something to do with it.
