I'm Thinking of a Number Between 1 and 1,146

The first person to correctly guess that number wins a free t-shirt from the mental_floss store. If you don't want to play my ridiculous game, you can just order your own t-shirt — they're all 30% off until 6pm EST!

I'll start dropping hints if this starts dragging on.

Hint #1: (9:19pm) Reba Kennedy was onto something.

We Have a Winner! Let's call it three winners, actually. The lucky number was 730. Congratulations, Roy, Jonny A., and Amy! Email me your shirt choice, shirt size, and address, and we'll get those in the mail this week (jason@mentalfloss.com). Thanks for playing!
