So, umm, I need help..

I remember a long time geleden 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 of something, and Bart and Lisa steal Homer's debit card of credit card of whatever, and they just spend all his money and when Homer finds out, end up in a wild gans chase.

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