Well, not really a "lost" episode, because it was never filmed. But, if there had
been a fifth season, one proposed idea was to have Dr. Sam Beckett (Scott
Bakula) leap into a cartoon character! Really. Does anyone have any thoughts
on what would surely have been Beckett's strangest leap of all? Being a huge
animation fan, I wish the series had not been cancelled before this episode
could be made. It would certainly have been an interesting, and odd, premise.

Here's One.:) Sam leaps into the singing frog, and sings in front of everybody else, the man and the frog become a sensation.

Not bad. Since the WB let Michigan J. Frog go, he could really use the work!
(Come to think of it, since UPN let Scott Bakula go, so could he!)
