I hate frogs

A guy goes to see the doctor, because he's been a little too "well-endowed', shall we say. In fact, it's 25 inches long. Can't get any women to have sex with him.
Anyway, the doctor says there's nothing he can do medically, but sends him to see a witch that he thinks might be able to help.
Witch takes a look at the problem (yikes!) and tells him to go to a particular pond, deep in the forest, and talk to a frog that lives there.
"Ask the frog to marry you and each time the frog says no, you'll be 5 inches shorter."
Worth a try, he thinks, and off he dashes into the forest, as anyone in this sort of joke would.
Finds the pond and sees the frog on the other side, sitting on a log. "Will you marry me?" he calls to the frog.
Frog looks at him, disinterested at best,and calls back, "No."
Guy looks down, sure enough, he's 5 inches shorter. Hey, this is great, he thinks-let's try that again. "Will you marry me?" he asks the frog. Frog rolls his eyes, and shouts back again, "No!"
Twitch-the guy's down to 15 inches.
Well that's still a bit excessive, he thinks.
Down another 5 would be perfect.
So he calls across again, "Will you marry me?"
Frog yells back, "Look - how many times do I have to tell you?
No.
No.
NO!"
