Sen. Rand Paul (R-Ky.), who was unable to leave the Senate floor during his nearly 13-hour filibuster on Wednesday, joked Thursday that he considered using a catheter to avoid the need to use the bathroom.

"Well, see, the thing is I did think about it," Paul, who is a doctor of ophthalmology, told conservative commentator Glenn Beck on Thursday morning. "I've put them in before, and I really decided against it."

Paul, who phoned in to the interview, appeared to chuckle after his comment. Paul's office told Post Politics that Paul was, in fact, joking.
