Smoke bombed a couple of mole tunnels.

My brother had a mole problem in his yard and our older brother said he had the solution. Being the older bro we said come on over 'cause you just naturally listen to the eldest..

Following his instructions we put the end of a hose down the hole as far as we could. The other end of the hose was fastened to a 20# propane tank. We turned it on and let it run thinking them guys can't live breathing LPG.

Well, I looked at my brother and asked what happens if you throw a match down the hole?
He said he didn't know 'cause he had never done that.

The lite match went into the hole and we had little eruptions all over the yard. We don't know of the fate of the moles.

Oh, by the way, The mortality rate of the human race is still 100%.
