Can someone tell me about this?
I'll try my hand at this...
Back around 1997, Rick Rude had appeared in ECW. Their shows taped well in advance, so it was a long time before the clips of him on it were shown.
A few months later, Rude joined the WWF as a manager/enforcer for D-Generation-X. At the time, Raw had yet to go live weekly. So, he appeared on a taped Raw once.
During the time between when that Raw was taped and when it was aired, Rude's WWF contract ran out (I'm assuming), and he signed one with WCW. WCW Nitro was already live every week at the time, so when Nitro came on, Rude appeared on there.
He also appeared on the taped episode of Raw, which aired about the same time, as well as the ECW show.
If anyone can correct me, go right ahead.
Wonder how much that confused the marks?
