Currently the zenith of stupidity is in the White House.

However, I will NEVER EVER bet on the zenith being reached in this area:

-- During WW2 the US Army developed a hand grenade that would only arm after traveling 20 feet, and then it would explode on contact. At a demostration at Aberdeen Proving Grounds an officer who was uninvolved with the development and didn't listen to the briefing told the assembled crowd that it was "as safe as a baseball." So he threw it WAY up in the air and vanished when he "caught" it.

-- A chap with whom I am intimately associated tried to determine if a cleaning rag was wet with water or ammonia -- it was ammonia. Eyes streaming and throat burning I he struggled to a Coke machine which dispensed only carbonated water -- and the mild acid neutralized the ammonia.

No, we haven't reached the zenith yet.
