Quote from Tim in What You See is What You Get
Al: Before you sand this table, will you reimburse me? [Tim starts sanding the table with the drill attachment] It's stuck in the middle! Move it around! Don't leave it in one spot! You'll wreck it! Tim: How do you know? [Tim stops sanding and finds a large circular hole in the table] Now all we need is a square peg. Al, hop in!
