Bin Diving
Sifting through boxes for many, many hours, searching for rare and/or obscure comic books.
Kirby: Hey Steve! Did you make it to the "Lost" panel at Comicon?

Ditko: No. I needed issue #47 of Shang Chi: Master of Kung Fu, and Captain Carrot #5, so I went bin diving.

Kirby: Did you find 'em?

Ditko: Nope.
