They had a tradition where if either one had a really bad week or day they would get together & watch a show where they couldn't but help but laugh.
Their favorite was "Wipeout". It was one of those game shows were crazy people go against each other & have some of the funniest spills & falls.
It was therapeutic to them, while watching they didn't have to worry about bad guys or victims or anything else really. They could for an hour laugh & let the bad feelings drain away for a little bit. They relished this small bit of time together. Made them feel normal again.
Don't own either CSI:NY or Wipeout.
