Celebrity impersonators are nothing new.
It's also no surprise that the most popular costumes for parties and Halloween are those that resemble well-known cultural, historic, or mythological figures.

According to a conversation I had over lunch with one of the TTBs, the reason Nitrozac and Geekculture sponsored the After Y2K Lookalike Contest was to identify possible understudies and replacements for current characters in the coming new year. Please understand, this is just a rumor. You know how much a TTB likes to joke, but consider the implications.
