I had a classic sitcom moment at work this week.
Sitcoms, that mixed bag television staple, fail or succeed based on how well they walk that 
ordinary moment becomes absurd line.  Great ones (
Seinfeld) tread the line masterfully; they know exactly when normal people and situations must become absurd.  Terrible ones (look for the CBS logo) do not know the line even exists.  (Quick aside: 
It's Always Sunny in Philadelphia tap dances along some silly-straw line that travels into some other dimension.  Fantastic!)
…I am a thorough hand washer.  I mean, you'd think I was heading into surgery.  But, I'm a haphazard hand drier.  We have paper towels in our restroom at the office.  One is not quite enough; two is overkill.  Usually, the Poor Richard in me only grabs one towel, and the damp hands resulting are between me, my jeans and my desk chair.  No big deal.
I exit the restroom.  In the hall stands Buck Buck
* and some other guy.  "Hey, TonyN, this is Chris from LargeCompanyThatIsAnImportantClient."  Reflexly, I extend my hand, "Nice to meet you," and they move on down the hall.  Back in my edit bay, horror careens through my head.  "Wet hands.  Just water!  Why didn't I use two towels!?!  Oh, god, he'll think--  Obviously, that's what I would think.  Go apologize; go explain.  Don't be an idiot!  Do something to explain it away: 
hey, this new waterless hand cleaner stuff is neat-o!  No, no wait.  Gotta have a plan.  Maybe I could--  Oooh, I know!  First, I'll go back into the bathroom.  Then, I'll get a bucket of water…"
Luckily, I fought off the impulse to become a sitcom character.  Instead, I went back to editing my little T.V. show, accepting the fact that some stranger thinks that I just pee-shook his hand.  Sure, it sucks, but I think I've seen enough sitcoms to know that the outcome of attempting some scheme of explanation or cover-up would have gone sorely awry.  I mean, who knows?  I could have lost my job, gotten arrested, and been deported had I followed through with sitcom behavior, right?
