On Big Boy's Power 106 Radio show - which at the time I think was later in the evening, early 90s - he had two bits that stick out in my mind, that I've never found any evidence of.

• Hebrew rap - I think a short 'freestyle' session where he rapped in Hebrew, which I'm almost certain was anything but Hebrew
• Shakin' My Ass - Big Boy claimed he and everyone in the studio were butt naked and dancing, to a song in the background that sounded like, but def wasn't SuperSonic. Big Boy would yell the main lyrics and the studio would respond with whats below in parens. The lyrics would get pretty wild, along the lines of:

I feel like 
shakin' my ass, shakin' my ass, shakin' my ass
(shake, shake it!)

I feel like 
squeezin' my breasts, squeezin' my breasts, squeezin' my breasts
(squeeze, squeeze em!)

I feel like 
feelin' my nuts, feelin' my nuts, feelin' my nuts
(feel, feel em!) // not sure about this one

LEFT CHEEK!
(wiggle wiggle!)

RIGHT CHEEK!
(wiggle wiggle!)

The left/right cheek part he'd repeat til the 'ran out of breath'.

At the time he was still obese so this was him kinda having fun with that, and me and a friend could not stop laughing at the thought of him actually doing that in the studio.
