Malfunction Indicator Lamp

Thursday on my way to work, one of my indicator lamps begins blinking at me. I was close to work so drove the rest of the way since the temp of the car was fine and it was driving ok. At first, I thought it was a check oil, so call the husband to ask him how do I add oil to my car. Checked the oil, and it was fine. Go back to the car and realize that it's not the little oil lamp blinking, but an outline of an engine with the words "Check" in the middle - FRICK! I pull out the ol' manual and am told this is my Malfunction Indicator Lamp. It reads that I have issues with emissions, and should either check that my gas cap is screwed on tightly or get to my dealer ASAP. FRICK! At the dealer after work, my car gets hooked up to a little device that spits out codes to the service guys (pretty cool that my car talks in codes with what's wrong with it), then Ben (the really nice service guy) types the code in at a Honda website, and I am told that Honda will be picking up the tab on this one to have it fixed! WOO-WOO! I saw my entire tax refund check vanish and reappear that afternoon! Thanks Penske Honda Service guys - you made my day!
