Stuffed up sense of humor

I have a terrible head cold and it's making me miserable. Food has lost its taste and my shows have lost their humor. Last night I watched My Name Is Earl, The Office, and It's Always Sunny in Philadelphia and either all three were just eh, or my headcold has dulled not only my sense of smell but my sense of humor. I'll have to rewatch when I'm feeling better to see which it is.
