A doctor and his wife were having a big argument at breakfast about their sex life. She complained that he was not a very good lover.
"Well, you aren't so good in bed either!" he shouted, and stormed off to work.
By mid-morning, he decided he'd better make amends and phoned home. After many rings, his wife picked up the phone.
"What took you so long to answer?"
"I was in bed."
"What were you doing in bed this late?"
"Getting a second opinion."
