No no no, I know what it is.
I'm sorry I can't tell you the name of the episode, but I know what you're talking about.
Marge and Homer were trying to get away from Bart and Lisa, and there was sort of a "catch me if you can" parody, where they were in an airplane, and, yeah. In the end they were in a hotel, and Bart and Lisa sneak out to give them some alone time, but Homer and Marge sneak out too and they end up in the same place, and Marge and Homer think Bart and Lisa followed them.
I'm sorry it's kinda vauge, but those are the best details I could give.
sweatdrop But I know what you're talking about.
EDIT: I googled it, and the episode is called "Catch 'Em if you Can." Here's a wikipedia article on it:
