How well do you like your lawn? I'm a big proponent of excessive amounts of petroleum poured down the holes and a match thrown it.
If you get lucky, the first hole will have a critter in it and he will run out of the hole with his tail on fire. This of course will have a some squealing sounds with it, some from the wife but mostly from the critter. When he runs into the next hole (tail still on fire) it will set off a chain reaciton of sizzling critters and really, a pretty cool volcano-like show of flame from various spots in your yard.
