I need to know the exact line and who says it; its a quote from the Simpsons, but not one of the hundreds of usual funnys we all spout on here.

I think it's either Flanders, Homer or a generic salesperson-type who says this about the art of sitting:

"From the noblest king to the lowliest peasant, everyone loves a good sit"

I know that's not correct though, and Google hasn't helped. Can any of you bright sparks help me out please?
