found $1 on the ground in a store in Ohio once
found $20 on the floor on a bus and was lucky the bus driver didn't see me grab it
found $5 on the ground near a bus stop and asked a guy if it was his and he said let me check, then he said it was my lucky day and handed it back to me
found $20 in Target and gave it back to the lady that dropped it (I am a good Christian right)
found a Dennis Eckersley Upper Deck baseball card on the ground but it was folded (probably because someone besides myself found out that he is kind of a snob/jerk but I still have it)
found a mountain bike on a trail and left it there (re: Christian)
found a 4 megabyte RDRAM expansion cartridge in my used N64 after I bought it ($20 total for N64 this was years ago too)
