I also seem to recall that his wife, Kitty Dukakis, had a bit of a drinking problem. That was the basis of a rather distasteful (but funny as hell) joke going around at the time:
Q: What do you call hundreds of empty beer cans and liquor bottles strewn all over highways in Massachusetts?
A: Kitty litter.
Heh-—good one.
SNL did a hilarious Dukakis debate satire which is sometimes rerun even today. Dukakis is seen behind the rostrum ready to debate-—as he slowly rises as if on an elevator to reach the mic-—(he’s real short). LOL.
