Have you ever gone to see any tribute acts?

Live Acts
They are not my personal cup of tea but I know some people find a night with a tribute act to be a good laugh and some of their names are hilarious. Do you know of any particularly amusing one?

Youtube Acts
Oh and get into embarrassing and hilarious tributes on youtube. They are plentiful.

I only know the Britney VMA one...

Not what I meant. I mean travelling tribute acts who imitate the artist or band.

For example.

AC/DShe
Alike Cooper
LayD Gaga
Mentallica
By Jovi
Slack Sabbath
Rabbi Williams
Red Hot Chili Beans
