Yeah, Ian does that every now and then. It's pretty funny. To be honest, I find myself thinking it sometime too. I hear a joke or read something pretty funny, but instead of laughing I'll just think "LOL" or "ROFL". Then, of course, I realize how sad that probably is, and I try to correct myself, but it's usually to late.
Ahh..nothing like a nice day at work when you've finished all the projects on your plate.
