Tom

Tom, played by Dave Foley, is Richard's friend and Christine's ex-boyfriend.

History
Tom was set up on a date with Christine by Richard in the second season. The date ended in disaster with Tom getting diarrhea and Christine running into Daniel Harris. Tom becomes obssessed with Christine and triess to get a second chance with her, but she usually can't even remember his name. In the fifth season Richard sets them up again and they end up in a relationship. Christine was only using him for his money, and he would ultimately break-up with her because he found her attempt at seduction repulsive.
