A man enters a barber shop and asks the barber “how long do I have to wait for a haircut?” The barber replies, “two hours mate.” The man leaves and returns the same time the next day. “How long do I have to wait for a haircut?” he asks the barber. “Only an hour mate” the barber replies. The man then leaves and returns the same time as usual the next day and asks the barber “how long do I have to wait for a haircut?” The barber replies, “Take a seat. Only forty five minutes”. The man then leaves and as he does so the barber heads over to his friend and says, “That man comes in every day and asks how long does he have to wait for a haircut yet when I tell him, he leaves but keeps managing to return the next day. Follow him and find out what he’s up to.”
The barber’s friend returns after a while laughing hysterically. He says to the barber, “I followed him over to your house and it seems his doing the hanky-panky with your wife”.
