Three bubbes were sitting around and bragging about their children.
Freda says, "Benny graduated with a first class honours degree from
Oxford and he's now a doctor making £250,000 a year in Harley Street."
Kitty says, "Sidney graduated with a first class honours degree from
Cambridge and he's now a lawyer making half a million pounds a year
and he lives in the City."
Ethel says, "Abe never did well in school, never went to university
but he now makes one million pounds a year working as a sports
repairman."
The other two women ask, "So what's a sports repairman?"
Ethel replies, "He fixes football matches, rugby matches, cricket
matches....."
