I wondered what the cheapest win you've ever scored in a game, any game was.
One that comes to my mind is playing Mario Kart Wii online in Moo Moo Meadows and being in last place on the last lap with the bullet bill power-up. I saved it for when I thought I could still possibly cross the finish line with it. A split second after I use it someone else uses a lightning power-up. So while I zoom ahead invincible everyone else gets shrunken and slows down. My roommate in first watches in disbelief at my luck as I pass him right before he reaches the finish line for the win. I savored finally having the unbalanced power-up items actually work in my favor for a change.
