St. Paul police said Brent Todd Friest, 39, a Radcliffe, Iowa, pig farmer, was consulting with the specialist Wednesday at United Hospital when he commented that "it must be hard getting a date being a psychologist," the St. Paul Pioneer Press reported Friday.
The psychologist ignored the comment, but Friest soon told his son to leave the room so he could tell a "dirty joke" to the psychologist.
"I bet you a dollar I can play with your boobs without touching them," Friest allegedly told the doctor.
He then allegedly fondled the psychologist's breasts with his hands and gave her the dollar.
The woman called hospital security and police arrested Friest -- who admitted to the incident when speaking to officers, policed said.
"He admitted that his conduct was inappropriate and that he thought it was humorous at the time," the complaint said.
Friest was charged with fifth-degree criminal sexual conduct and taken to the Ramsey County Jail in lieu of $1,000 bail.
