I don't know, folks. Allow me to play devil's advocate for a moment. A big part of humor is the unexpected punch line. I expected to see a snake of some kind and I saw a man's face. It tickled my funny bone because of the absurdity of it. But I in no way would ever laugh at any kind of joke meant to put people down. If the man had really been an albino, I would have been ticked off. But he's not. Perhaps this joke would be considered in poor taste by some, but cruel? It seems too absurd to be taken so seriously. Just my .02.
Apply a different physical characteristic to the same joke. Still funny?
What if the title was something like "ID Black Morph, Please", and was opened to show a really dark black person. Follow that up with, "I keep him in a 500 gallon tank..." Is this still funny? Afterall, it still fits your definition of being unexpected, which, as you say, is a "big part of humour"...You're still laughing, right?
What about "Help! Neurological Disorder", and the topic opened to show a mentally disabled individual? You still laughing?
The point is...it's rude. Is it criminal? Nah. Is it evil or vile? No, not really. Is it cruelly inteded? No way of knowing for sure, but doesn't seem to be. Does that make it right? Absolutely not.
When you are in a public place, speaking to a public audience, it is typically a good idea to keep your insensitivity, bigotry, and personal prejudices to yourself, rather than toss them about as if everyone is expected to follow suit. This is a public venue, and this topic is a public speaking engagement. It may not be blatantly wrong, but it sure does speak voumes for the character of the individual making the "joke"...
There is a thing in this world called common decency and respect. A topic of this nature shows a complete lack of both, and personally, I don't find that humorous in the least. In fact, quite the opposite, I find it very sad and disheartening.
But you can go ahead and keep laughing, if you like...:headbang:
