You've got red and green bags under your eyes.
You're serving reindeer pot pie.
When you hear, "Sleigh bells ring, are you listenin'?" You scream, "No! I'm not listening!"
You climb on your roof and start shooting carolers with your air gun.
You think you hear your Christmas tree taunting you.
Instead of spending time with family, you're watching some guy make photo copies.
You've got eggnog coming out of your ears.
Tinsel rash.
