sounds like a good excuse to try one of these "nice" air guns (actualy a cheap yet accurate will do...but that wouldn't be as fun
) put a laser on it and sit at night quietly popping 'em. It could become your new favorite past-time.
OR....go to a local animal shelter and find the most hideous, scruffy, he-man of a pissed-offed looking Tomcat. Put ephedra in his water, grab a bag of popcorn and enjoy the show!
