"Centipede" joke

One day the big animals and the little animals decided to have a football game. As the first half went along, the big animals were scoring at will. Every time they got the ball they would run it in for a touchdown.
Then came the second half…
First play: The elephant runs the ball up the middle. WAP!! Tackled for a five yard loss.
The little animals go back to the huddle cheering and congratulating each other.
“Who made that tackle? ” asked the ant.
“I did, ” said the centipede.
Second play: The rhinoceros runs the ball up the middle. WHOMP!! Tackled for another five yard loss.
Back in the huddle the flea asked, “Who made that great stop? ” “I did, ” said the centipede.
Third play: The gorilla tries an end sweep, led by the hippo throwing the lead blocks. SMACK!! Centipede tackles him for a ten yard loss.
Back in the huddle, the gnat asked the centipede, “Where were you in the first half? ”
The centipede replied, “Puttin’ on my shoes! ”
