It's pretty obvious: Celebrity product endorsements, whether intentional or not, are good for business.

WWJ reports that sales of the t-shirt have spiked.

So far Pure Detroit has received 400 orders for the shirt. The company is donating 25 percent of its sales of the shirt to the ALS Association.  3-thousand dollars has been donated so far.
