OK, this really isn't a random fact... but here's a little random Math humor for ya...
Question: Why is this a mathematical limerick?
( (12 + 144 + 20 + 3 Sqrt) / 7 ) + 5*11 = 92 + 0 .
A dozen, a gross, and a score,
plus three times the square root of four,
divided by seven,
plus five times eleven,
is nine squared and not a bit more.
