The Two Barbers Riddle goes like the following (via Brainpower):

A man was in a small town for the day, and needed a haircut. He noticed that there were only two barbers in town, and decided to apply a bit of logical deduction to choosing the best one. Looking at their shops, he saw that the first one was very neat and the barber was clean shaven with a nice haircut. The other shop was a mess, and the barber there needed a shave and had a bad cut besides. Why did the man choose to go to this barber?

After purchasing the CONAIR Home Haircut Kit, the riddle is happening for real inside Schenley House.
