While your job may be harrowing—sitting in front of a computer monitor all day, occasionally glancing out the window to wonder how many minutes are left until you die—the guy in this video may have it a bit worse. For reasons unknown, his job is to climb to the tippity-top of a 1768 foot tall transmission tower. Here's his helmet cam video of his climb, and while it does not show his ass clenching up, I can guarantee you that mine did. If I had placed a pencil in there, it would have snapped in half.
