So an engineer, a physicist, and a mathematician move in to a new place together.

Their first night, a fire starts in the house. The engineer wakes up, sees it, douses it in buckets of water, puts it out, and goes to sleep.

The second night, another fire starts. This time, the physicist wakes up, sees it, calculates exactly how much water to use to put out the fire, pours exactly that much water on the fire (plus or minus experimental margin of error), puts it out, and goes to sleep.

The third night they decide to search for fires before bed.

The engineer does a quick sweep of the house, convinces themself there are no fires, and goes to sleep.

The physicist searches a while longer, convinces themself there are no fires, goes to sleep.

The mathematician searches and searches, but can't prove there are no fires, and so can't go to sleep. After some thought, they set their own fire and go to sleep, thus reducing it to an already solved problem!

The man below says, "You must work in Management."

"I do," replies the balloonist, "But how did you know?"

"Well," says the man, "You don't know where you are, or where you're going, but you expect me to be able to help. You're in the same position you were before we met, but now it's my fault."

Surprisingly, I think the parent's answer is totally helpful, and never thought he "is a mathematician".

"How can a post hit frontpage with no comments?" "Because people upvoted it without leaving a comment." - I actually find the answer very enlightening.

I would like to sincerely thank you for giving me yet another site I can waste time on.
