A man goes into a drug store and asks the cashier for some condoms. The cashier asks, "What size?"
The man replies, "Size? I didn't know they came in sizes."
"Yes, they do," she says, "What size do you want?"
"Well, gee, I don't know," the man answers.
The lady is used to this, so she tells him to go to the back yard and measure his penis by sticking it into each of the three holes in the fence. While the man is back there, the lady sneaks around to the other side of the fence and spreads her legs behind each hole as the man tests it. When they return, the cashier asks, "What will it be? Small, medium, or large?"
The man replies, "To hell with the condoms, give me a hundred feet of that fence back there!"
Snow White and the Seven Dwarfs are roaming in the forest when they come across a lake. The water was enticing and Snow White decides to take a bath. So she tells the Dwarfs to turn around while she is taking a bath in the lake. The Dwarfs protest vehemently because they want to take a bath too.
Snow White relents and says "When I get into the water and you hear the splash, you can turn around." Snow White undresses and as she is about to jump into the water, at that very moment, she is startled by a frog who jumps into the water before she can. The moment the Dwarfs hear the SPLASH, they turn around and see Snow White standing NAKED.
Now, given that this incident is an idea for a TV ad, what product is being advertised?
