Farmer Gossman goes to the vet and says, "My horse is constipated..."
The vet says, "Take one of these pills, put it in a long tube, stick the
other end in the horse's ass, and blow the pill up there."
Farmer Gossman comes back the next day, and he looks very sick.
The vet asks, "What happened?"
Farmer Gossman answers, "The horse blew first."
