The Law Of Unintended Humor

Comics Should Be Good has a regular featured called "Intentional or Unintentional?" in which the question is posed as to whether something that readers find funny in a comic was actually intended to be so. The classic example is from the old Batman comic featuring, wait for it, "The Joker's Boner."
(Presumably, in this context, boner means "error, " and not one of its other meanings, which is part of what makes it funny, and which leads you to wonder whether it was an innocent use of a common bit of slang, or if the intent was to get away with a lewd comment under the guise of seemingly innocent slang.)
Now I admire well-crafted deliberate humor as much as the next guy (but less than the guy after that), but I have to say that sometimes I find unintended humor to be much funnier. Why? In part I suppose because it's more naturalistic. Also, there's the added bonus of spotting something that might have been missed, which makes you feel clever.
Mostly, though, it's funnier because of how utterly clueless the person responsible for the humor usually is about the whole thing. What makes it even funnier is that no matter how much you explain it, said person may very well never understand why what he or she said or did is funny.
The two best examples of unintended humor I've encountered were both uttered by my mom. (Who will probably be annoyed by me mentioning this, even though neither one reflects negatively on her in any way. Still, sorry mom.)
The first one was just a simple slip of the tongue in which she said "cricket" when she meant "critic." It was funny, for me, because there's an episode of The Simpsons in which Homer says "cricket" in place of "critic," only in Homer's case it was the result of being an idiot - which, I want to make perfectly clear, my mother is decidedly not - not simply misspeaking.
So really, it wasn't so much that I was laughing at my mother as I was laughing at what her misspeaking brought to mind.
The other was something I overheard her saying on the phone once. She described someone as being "a friend of Dorothy."
This person literally was friends with someone named Dorothy, but hearing my mother inadvertently use the term - which is another way of saying someone is gay - just struck me as hilarious, especially because she had no idea that what she had said was funny.
Anyway, after reading the latest "Intentional or Unintentional?" today these memories came to mind and I thought I'd share them with you.
