This is actually the most economical and easy way to do this that I've heard of. Also it'd be fun lifting up the swatter to see what kind of expression and pose you caught them in. >u<
It's a little taste of the same kind of surprise you get when opening a pack of tcg cards. Which idiots look embarrassed or uncomfortable or shocked or seem to be blushing a bit too much? What random goofy poses do they each get caught in and wouldn't it be fun to find someone every once in a while who played along and posed in a silly or provocative way just before the swat? Very fun =u=
