I don't remember any specific ones that I joined in. I thought a really funny one was the one where everyone had a bunch of people in their sigs, like...
"PSYCHOTIC IS MY MAIN PAL
SPIFFING CHEESE IS MAH HUNK OF CHEESE SISTAH
CRASH IS MY LEFT SHOE
LEEZA IS MY CAT GUARDIAN SISTER
RAISTLIN IS MY OLDBIE BROTHER"
Also, EGG was pretty funny.And the EoTW fad of being a communist.
