I've still got a gat gun kicking about some where. Great fun.
What kind of ammo was he using when he nailed your coupon? Dart, cork or pellet?
I always used to practice for ages firing the corks so when the carnies came to town I figured I'd be a crack shot at it. Every time you fired their ones the cork ended up about 3 metres away from where you were aiming. Cheating gypos.
