What ep. PLEASE!! - Homer- "Let's see where he's going with this.."

I thought this line was in "Bart's Comet", but snpp says no. Can anyone help?

The Great Money Caper

Sweepings Fist : It's not just a noun, it's a verb.

*Please note* -- I have a tendency to post while stoned. Apologies in advance.

Can you explain the scene/quote by any chance? The ep's not up on snpp yet.. Fanks
