Can't figure out Kanped's. Here's two new ones, simple if you know what to look for:
1) Which weighs less: a pound of feathers, a pound of bricks, or a pound of gold?
2) You're hired at the US Mint, in charge of procuring supplies for making money. Your first assignment: purchase enough materials to print $1,000,000 in $1 bills. The first supplier on the list of suppliers that you call is the sales manager of a paper factory which uses recycled wood to make new paper and cardboard products. How much of her paper will you need?
