2. "Here it i . . . ."

3. Surprised. Usually something like that is preceded by "Here, hold my beer".

4. Is his name MacGruber?

5. Amazing. They actually have a video of it.

And no one try's to stop him.

6. Well, they did have the foresight to back away.

[RebelOne]

7. He definitely deserves a Darwin award. n/t

[HappyMe]

8. Oh boy.

A hold my beer moment for sure.

I wonder if those guys that backed away tried to tell him that it was a poor idea at best.

9. The 2nd-fastest man-made object is a manhole cover. And it might be actually be the first.

The fastest known is the Helios probe, at some 43 miles per second, launched in the mid-'70s.

The second-fastest is a metal cap (basically, a thick manhole cover) that was welded to the top of the shaft that contained an underground nuclear bomb during a test in the 1950's.

There was a high-speed camera pointed at the plate when the bomb went off. Despite the speed of the camera, the cover was caught in only a single frame during its flight.

Based on shutter speed and the frames per second, the cover had a minimum velocity of 41 miles per second.
