#1 I make weapons in my spare time old-school fire, hammer and anvil but the last time I made one someone called the Fire Department... so I ended up giving 4 curious firemen an impromptu blacksmithing class in my backyard while their truck set in front of my house with the lights on for an hour.
#2 A dude once pulled a switch-blade on me in an alley, I stepped up on him and said, "What are you going to do with that, punk!" at which point he handed me the switch-blade and said, "I was just going to give this to you because you seemed like the kind of guy that would like to have it." and ran away.
#3 When I was younger I used to bet people at parties/bars $20 that I could use a log chain to hand pull a 70's model Cadillac Hearse across Lowes' parking lot (because it was the biggest level one in town) until I got a crowd gathered there in the middle of the night. I could get it going fast enough to hop on the hood and 'surf' the last half of the parking lot, making good side money for the next adventure.
