For fun, here's a problem I tried to solve once. With help from the interbutts, I did solve it. I'd be interested to see what /sci/ comes up with. The actual problem was about bundling fiber optic cables, but it is stated easier as follows.

You have an urn with 169 balls. There are nine colors, 19 of eight colors and 17 of the ninth color. You draw 19 balls. What are the odds that you have drawn at least one of every color?
