A young couple trying to live up to a snobbish lifestyle went to a party. The conversation soon came to Mozart, "Absolutely brilliant???lovely???oh, a fine fellow???a genius, Mozart was."
The woman, wanting to get in on the conversation remarked, "Ah, Mozart. You're so right. It was just this morning that I saw him getting on the No.20 bus going to Erdington." There was a sudden hush and all eyes were turned toward her. The husband pulled her aside and angrily barked, "We're leaving right now."
In the car on the way home the wife turned to the husband and said, "You???re really mad about something aren't you?" "How could you tell? My goodness! I've never been so embarrassed in my life! You saw Mozart take the No.20 bus to Erdington, huh? Everybody knows that the No.20 Bus doesn't go to Erdington!"
