1000ft-Tower Crawler

On the 100th anniversary of the Tower of Babel, Steve decided to test the structural integrity of the building by climbing it while wearing a pair of high-visibility, neon-green Crocs.

After 17 hours and 32 minutes, Steve reached the top of the tower, where he was greeted by a confused-looking pigeon.

Steve's next achievement challenge: climbing the Eiffel Tower while reciting the entire script of "The Big Lebowski" backwards.
