My boss called me with a problem that had been really bothering him and his *smarter* employee for a bit and after hanging up with him I called him right back and said (essentially -- too complicated to recount here) if they took the thought to the bitter end the problem would disappear.
He paused and said,
"Oh my god I can't believe we didn't think of that.. Emily... you are dangerously brilliant."
Just felt so good because I know that I bested some pretty smart people.
