The Denver Broncos quarterback said "Omaha" 44 times in last week's game. The Broncos play the New England Patriots on Sunday.
The Hotels.com travel site says it will offer a 15 per cent discount on Omaha hotels through June 1 if Manning yells about Nebraska's largest city at least 50 times.
Five Omaha companies have also pledged to donate $500 to Manning's foundation for at-risk youth for every time he shouts "Omaha."
So Manning's "Omaha" calls from the line-of-scrimmage could pay off if he doesn't change his routine to throw off the Patriots.
