Doug (1991)

Season 6: Episode 7

When Doug worries he is only average, he decides that to make his level of importance higher he should be a collector of unusal and (hopefully) valuable items. So he goes to a flea market with a valuable collecters item book looking for rubber tub stoppers and bowls, but someone has already gotten to them. Meanwhile, Roger gets on Mr. Bone's good side to get himself out of detention and Skeeter asks the A.V. Nerds to help him find the Lucy Duck Monster using A.V. equipment.
