here's one for the current time

NewYear's Ned - General out-of-shape bum who seems to go into hibernation 11 months of the year, and immerges wearing the same clothes every Janurary 2nd. He then enters the gym after purchasing yet another Annual membership, because he knows "this year is the year." Just as strange, he seems to disappear back into hibernation without saying a word on February 1st, not to be seen again for 11 months.
