I did some background reading for my Steve McQueen tribute meme. You great people really do think alike!
From wiki...
After discovering a mutual interest in racing, McQueen and Great Escape co-star James Garner became good friends. Garner lived downhill from McQueen, and McQueen recalled, "I could see that Jim was neat around his place. Flowers trimmed, no papers in the yard... grass always cut. So to piss him off, I'd start lobbing empty beer cans down the hill into his driveway. He'd have his drive all spic 'n' span when he left the house, then get home to find all these empty cans. Took him a long time to figure out it was me."
