An old guy, a young man, an old woman, and a young women are all riding in a train. The two women were facing the two guys in the same compartment.
As the train was going crossing the countryside, it enters a tunnel, and everything becomes dark. While in the tunnel, you hear a KISS then a SMACK.
When the train leaves the tunnel, the young guy is rubbing his face as if he was smacked. The old lady thinks:
“He must’ve tried to kiss the young lady and needed up getting smacked.” The young lady thinks:
“He must’ve tried kissing me and ended up kissing the old lady and she smacked him.” The young guy thinks:
“The old guy must’ve tried to kiss the old lady and she tried to hit him but hit me by accident.” The old guy thinks:
“On the next tunnel I am going to kiss my hand again and smack the young guy again.”
