Beetle Experiment

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!!"
