Someone posted this clip on "that other site". It's from 1995. Howard has Rhonda Shear in the tickle chair and she pulls his hair. Now this was during Howies, Louis the XIV hair style.
Notice Howard's scalp is visible!!!
His hair was obviously thinning then and he goes bonkers about Rhonda pulling his "hair". There's no question left in my mind that this is the smoking gun about Howard's wig/hair system.
