The Marquis de Sade
The MDS was a kinky French aristocrat & author-and whose very name is the basis for sadism-who was thought to be SO crazy even Napoleon himself had him locked up.
Vlad the Impaler
VTI was a brutal Romanian leader-who served as the basis for Bram Stoker's classic book Dracula-whose "speciality" was "impaling" his enemies-and allies-on wooden stakes.
Before there was Jackass & YouTube, there was Andy Kaufman whose antics-such as pro-wrestling & his alter ego Tony Clifton-would seem "tame" by today's celebrity standards.
Ozzy is one of the craziest-and drugged out!-rockers of all-time having bitten off the head of a bat onstage-true story!-and pissed on The Alamo while wearing his wife's dress which got him BANNED from Texas for years.
Wendy O. Williams
WOW was lead singer for The Plasmatics & dubbed The Queen Of Shock Rock for, among other things, blowing up a car on national TV & for getting into fights with cops
Frankly, I'm not sure how really "crazy" KR is since he once said the Rolling Stones "bad boy" image was "invented" by their record company to sell more records, but he's "crazy" enough for me!
I wasn't what you'd call a big fan of LL, especially when she went all batshit crazy, but then she posed for-who else!-Playboy so THAT helped to change my mind about her!
And here's one of my NOT-so-favorite "crazy" persons . . .
I used to be a fan of KO until I realized just how batshit crazy he really is; like, for instance, he once said how Fox (Non) News "hurt" this country MORE than 9/11. Yeah.
Now THAT'S some crazy shit!
