The blonde wife came home from her first day commuting into
the city. Her husband noticed she was looking a little peaked
and asked, "Honey, are you feeling all right?"
"Not really," she replied. "I'm nauseous from sitting backward
on the train."
"Poor dear," he said. "Why didn't you ask the person sitting
across from you to switch seats for a while?"
"I couldn't," she replied, "there was no one there."
