The SarcMark is a $2 downloadable punctuation mark that denotes sarcasm. What a great idea!@ (I was too cheap to download the real thing)

The official, easy-to-use punctuation mark to emphasize a sarcastic phrase, sentence or message. Once downloaded to your computer or cell phone, it's a quick key-stroke or two to insert the sign where you want, when you want, in your communications with the world. Never again be misunderstood! Never again waste a good sarcastic line on someone who doesn't get it!

I don't know about you, but I'm from the school of "if you can't tell I'm being sarcastic without a special symbol, you don't deserve to know". Thank God only the best and brightest read Geekologie, amirite?@

Thanks to tsholl, who refuses to use punctuation even if his life depends on it.
