Cohost Brian Kilmeade and guest host Scott Brown, the former Republican senator from Massachusetts, were given tests that for reasons never fully explained were supposed to demonstrate higher levels of testosterone.
The segment started off on a positive note as Kilmeade used his hormones to tie a necktie while Brown tied a knot, according to a clip posted online by Raw Story.
But things quickly went south when they were asked by former Navy SEAL Derrick Van Orden, author of "Book of Man: A Navy SEAL's Guide to the Lost Art of Manhood," to perform the extra-manly task of changing a car tire. Kilmeade and Brown failed to put the car in park or use the emergency brake, and it rolled forward.
"Watch your feet, Elisabeth," Brown called out to co-host Elisabeth Hasselbeck, who had been leaning on the car.
Then, the vehicle almost came off the jack. Eventually, the men gave up.
Perhaps trying to make them feel better, Van Orden gestured to passersby on the New York City street where the segment was taking place.

Kilmeade also joked about it on Twitter:
