I bet I have that same segment on tape.
One of my favorites is the trunk-dick.
An 80 year old man is engaged to a 25 year old woman. He's concerned that he might not be able to have sex as often as she likes, so he goes to the doctor for a penile implant.
The doctor says they're now doing a new type of surgery... one that's much more effective and allows the man to experience more pleasure than he'd get with the old procedure. He goes on to explain that they'd remove his penis and surgically attach the trunk of a baby elephant in its place. The nerve endings will grow together and he'll never know the difference, except of course that he'll be bigger and stronger than ever before.
The guy balks a little at this and says, "Gee, I don't know... What do you think honey?"
His fiance has heard the words 'bigger and stronger' and with great feeling she says, "Let's do it!"
He has the surgery, and he heals up just fine. They try a little exploratory sex and find that things work even better than expected, so they announce their engagement.
At the prenuptual dinner the groom to be is seated between the bride and her mother. The bride is so thrilled with the new trunk-dick that she can't keep her hands off it. She reaches over to him and while her hands are hidden by the tablecloth, she starts to stroke it through his pants. It swells up nicely, so she unzips his trousers. The trunk-dick pops up out of the fly and lays on his lap, throbbing from the attention she's been giving it.
As the dishes of food are passed around from person to person, the trunk-dick rises up above the tablecloth, grabs a baked potato and goes back down out of sight.
Dinner comes to a halt.
The brides mother says, "Excuse me, but I'm not sure what I just saw... could you do that again?"
The groom says, "I would lady, but there's not room up my ass for another baked potato."
