A farmer asked the vet to come out to check on his favorite bull who wasn't doing well at all. After checking the bull's vital signs, the vet reached in his black bag and pulled out a rather large pill.
He forced open the bull's mouth and crammed the pill down his gullet. Suddenly the bull jumped up and took off like a banshee, jumping every fence in his way.
The vet exclaimed, "Well, looks like your bull is healed!"
The farmer replied, "Now give me one of those pills. I've gotta catch him!"
