Eric cutting his hair.

Not only was I (much like Alex) happy to see that wig go, I loved the way they handled the entire thing – from how pissed he was that having to deal with the V dealers in the basement made him cut it even shorter than originally planned – to the fact that Pam was the stylist – to Bill and Eric discussing the whole thing in the department store later that night, it was just an awesome scene that ranged the gamut from gross to funny and it makes me happy.
