What's the name of the phenomenon wherein you start telling your spouse about something that you think is "HEE-LARIOUS!," be it a joke (usually dirty/offensive) or a story about something that happened at work or whatever, and the minute you start to explain it, you realize that she/he is never going to find it even the least bit amusing and what the fuck were you thinking when you thought she'd actually find it funny, and as you continue down this never-ending bottomless free-fall of regret, you get more and more pissed at yourself for ever thinking this was a good idea and you end up feeling like a complete douche, most likely pissing off your spouse in the process, and you finally put yourself out of your own misery saying something like, "Eh... nevermind, it's too hard to explain and it's not really that funny, after all. Forget it."
While this pretty much happens to me daily at the crabbshack, tonight it happened while I was attempting to describe what rickrolling was to the Old Lady. See, I had just seen this great rickroll version of McCain's speech and, like a fucking moron, I thought I could describe the video to the Old Lady, somehow convincing her that it was funny and, because I was the one describing it so hilariously, that I was hilarious, as well.
It went something like this, "So, there was this hilarious version of the blue-screen portion of McCain's speech that someone totally rickrolled and they cut up a bunch of Obama's speeches and actually had HIM singing the lyrics and... okay, lemme backup... so, rickrolling is when someone tricks someone into following a link to a Rick Astley song/video... usually "Never Gonna Give You Up"... see, it's kinda like a phony phone-call but it always ends up with a Rick Astley song and... anyway, someone spliced together Obama doing the lyrics... but the real song was playing in the background and... and then McCain's just standing there with this confused look on his face and... and the crowd was... and see Obama's up there on the... and... he... uh... Eh... nevermind, it's too hard to explain and it's not really that funny, after all. Forget it."
There's gotta be a word for that.
I'm gonna call it an "anec-d'oh!"
