Explain to the taxi driver

A couple was going out for the evening. The last thing they did was to put the cat out.

The taxi arrived, and as the couple walked out of the house, the cat shoots back in. So the husband goes back inside to chase it out.

The wife, not wanting it known that the house would be empty, explained to the taxi driver "He's just going upstairs to say goodbye to my mother."

A few minutes later, the husband got into the taxi and said, "Sorry I took so long, the stupid thing was hiding under the bed and I had to poke her with a coat hanger to get her to come out!"
