Today (Jan. 30) is 'National Inane Answering Machine Message Day.' It's a day to celebrate those long annoying messages on your answering machine or voicemail... and there are none better than George Costanza's from 'Seinfeld!'

This cracks me up, no matter how many times I see or hear it. Jason Alexander (George) just nails this parody of the theme to 'Greatest American Hero!'

If you haven't seen this yet, this is pretty cool, too. Jason records a special message for actress Kat Dennings.
