One day, a blonde was left alone in a lab with a beetle. She examined it and decided to do an experiment.
She pulled off one of its legs, then asked it to run. The beetle obeyed her command.
Then, she pulled off a second leg and asked it to run. It did, but with a lot of difficulty.
Finally, she pulled the remaining legs off and asked it to run. It couldn’t.
“I have made a new discovery!” the blonde cried. “When you pull all of a beetle’s legs off, it becomes deaf!!”
