About twenty people this year have wished me "GOOD LICK" instead of "good luck."
Depending on who the message is coming from, that can be really funny, or just downright uncomfortable. Ya know?
And do you want to know something really uncomfortable? Doing a google image search for "lick" without the "safe for work" search settings enabled on your computer. I am pretty sure these were the only two pictures that came up that weren't just downright disgusting. Although there were a few people who could actually lick their elbows, and that's kind of cool, only because I can't even come close.
Search filters are a good thing. Auto-complete, not so much.
