Richard Madison (Jon's dad) fled through the halls of the office, trying to get to his meeting. He was sure that he'd make it on time, but he wanted to be there well before the meeting started, so that he could greet everyone as they came in.
On his way to the meeting, however, he accidentally bumped into Morty (one of the few janitors that cleaned up the offices). And that's when it happened.
"Excuse me," Richard said. Those two little words would change the course of Richard's life (well, until the seven days of Jon's wish were over).
Both men suddenly became dizzy and when their heads cleared, Morton picked up the briefcase that he must have accidentally dropped and continued on his way to his meeting. And Richy continued to mop the floor. Both of them had no idea that they had swapped their personalities, as well as their jobs.
