Try This Experiment

O’Malley and Murphy were in the pub having a pint and their usual disagreement.

Murphy was holding forth that the dog was man’s best friend.

Because they would argue over absolutely anything, O’Malley challenged him to prove his statement while contending that a man’s best friend would certainly be his own wife.

“If you don't believe me,” Murphy said. “Just try this experiment.”

“Put your dog and your wife in the trunk of your car for an hour. When you open the trunk, see which one is really happy to see you!”
