We all have bad days, even models. Alexandra Underwood knew it was time for hers when she managed to get belted by a swinging pendulum during her catwalk performance on "America's Next Top Model."

The models were tasked with working fashion along a catwalk that featured two swinging pendulums. After managing to skillfully strut through on the first lap, Alexandra perfectly timed her gait to get whacked by the stage piece, sending her tumbling.

Unfortunately for her, that wasn't the only misstep. The stage featured a long set of stairs leading down towards the catwalk. Alexandra probably clocked the best time down the stairs when she slipped and tumbled down them. She was apparently unhurt and continued her presentation.
