So, umm, I need help..

I remember a long time nakaraan I saw an episode of The Simpsons, and it's always stood in my mind as my favorite.
I just can't remember the title.

I think it's basically about them on vacation or something, and Bart and Lisa steal Homer's debit card or credit card or whatever, and they just spend all his money and when Homer finds out, end up in a wild gansa chase.

That's really all I can remember about it. All I'm asking is, does anybody know the name of the episode?
