Does anyone remember an episode where Rick made up an alias and chose the name Rodney Dangerfield? I wonder who used the name first, the comedian or the Ozzie and Harriet Show. It would be interesting to know if Rodney, the comedian, chose that name after watching that O&H episode.

from Wikepedia:
He took the name Rodney Dangerfield, which had been used as the comical name of a faux cowboy star by Jack Benny on his radio program at least as early as the December 12, 1941 broadcast and later as a pseudonym by Ricky Nelson on the TV program The Adventures of Ozzie and Harriet.

That's very interesting. Thanks for that info.
