Footbal in the Jungle

The animals were bored. Finally the lion had a great idea. "Let's play the game the humans play. Football. I've seen it on TV."
The lion's team received. They got their two firsts down and then had to punt. The mule punted and the rhino was back deep for the kick. He caught the ball, lowered his head and charged. First he crushed a road-runner, then two rabbits. He gored a wilderbeast, knocked over two cows, and broke through to the daylight, scoring six. Unfortunately they lacked a place kicker and the scored remained 6-0.
Later in the first half the lion's team scored a touch-down and the mule kicked the extra point. The lion's team led at half-time.
The lion gave a pep-talk in the locker room. "Look you guys, we can win this game. But we've got to keep the ball away from the rhino. He's a killer. Mule, when you kick off, be sure to keep it away from the rhino."
The second half began. Just as the mule was about to kick off, the rhino's team changed formation and the ball went directly to the rhino. Once again, the rhino lowered his head and was off running. He stomped two gazelles, skewered a giraffe, bulldozed an elephant out of the way. It looked like he was home free when, suddenly, at the 20-yard line, he dropped down dead. There were no other animals in sight.
The lion went over to see what had happened. Right next to the dead rhino he saw a small centipede.
"Did you do this?" he asked the centipede.
"Yes, I did," the centipede replied.
The lion yelled, "Where the hell were you during the first half?"
"Get off my back. I was putting on my shoes!"
