A drunk was visiting London with his wife Jen,

They were both on their way to see Big Ben.

Having trouble finding it they asked a policeman the way.

"Bus number 34 will take you right there," he did say.

Four  hours later the P.C.  passed and they were sat on the floor,

"Excuse me," said the policeman"I told you to catch the 34."

"Oh don't worry officer,"the drunk's voice slurred,

"The bus that just went by was the 33rd."
