I wasn't familiar with Didi, but just googled her... the few pix I found of her made her look a bit shrewish, but that in and of itself would never keep her from potentially being strangely sexy. BTW, though I mentioned her before, Rita Rudner has got (presently) a fairly respectable rack... maybe she's had a lift with or w/o modest implants done to counteract age... I don't know. The last few nights of her 'Ask Rita' show have been travelogues for Vegas casinos for some unknown reason... she's usually wearing slacks and a knit top during the pieces about New York, New York, Zoomanity, etc... and in some scenes, a quite decent amount of projection (of her surely well-supported bosom, as compared to her reasonably flat ribcage/belly below) was appealingly apparent.
LSG's got a bigger rack by far of course (more late-night fare for insomniacs) but sometimes her posture leaves something to be desired (that slouch thing). Of coures, LSG is WAY too hot to get delegated to the 'strangely' sexy category.
