What Should The Initiation Be, Precisely?

I know we're supposed to have an Institute Initiation, but I haven't thought of a cool enough idea on what it should be like. We want something vicious, don't we? But it can't be too vicious, can it... Suggestions?

Well, everything diabolical that we could make someone do would be really hard to prove that they actually did it. Like if we said they had to go on a hunger strike, how would we know that they hadn't stopped for a Big Mac on their way home from work? They could lie...

Exactly. I know, maybe they have to have the words "I SUCK" on their signature for 1 month!
