So a young man comes to his first ever Karate lesson He steps through the doors of the dojo and sees three groups being taught moves by an instructor He is directed to the first line where one of the Sensei's is teaching them how to block a hit The man quickly learns the move and advances to the second group, proud of his achievement The second line is taught one by one to perform a simple throw, but the man struggles as he has always lacked upper body strength After many tries he finally succeeds but he decides karate is just not for him. The young man turns around and walks towards the door, however on his way out the Sensei calls out his name and says: ""Hey, didn't you forget the punch line?""
