Somewhere in my big box of porn (a lot of which was converted from VHS to DVD), I recall a scene of Sharon Mitchell (pre-M.D) applying a green gel to her mouth, then swallowing some if it down to her gizzard, then giving Peter North an admirable blow job...

Green oral jel = Coke Stevenson
Process = XPT
Sharon Mitchell = XPT humor
Peter North's dick = also equivalent to Coke Stevenson
