What is the funniest thing you have seen during your time in the military?

Time and Distance from the Actual Oops Adds Unique Perspective. Watching a SM-2 Surface to Air Missile do a U-Turn and Come Home, Twice. It's funny as shit now, Not so much at the time.

James Adair A Marine artillery person(can't say artilleryman)sent for a bubble pump for a Howitzer and returned with one.

Watching a MSG tear open a chemlight wrapper, shake it and return it to supply for a replacement because it was broken (or I guess you could say it was not broken). We laughed the whole roadmarch about chemlight batteries.
