Among the friendly wagers going into the game:

Mayors
The mayors of L.A. and Cincinnati are putting their own money on the line. Los Angeles Mayor Eric Garcetti and Cincinnati Mayor Aftab Pureval agree to make a personal donation to the losing city's children's hospital — and to encourage their constituents to do the same.
Also, the losing mayor agrees to wear the winning team's jersey at an upcoming public appearance.
Zoos

The zoo of the city that wins the Super Bowl will change its logo on social media for a whole day to incorporate the logo of the winning team.
The L.A. Zoo's permanent emblem features reptiles, the California condor, rhinos, and a gorilla. Officials say they are confident the Rams will win and there won't be any tigers added to the mix!
We think the signature horns of the Rams would be a fitting replacement for the rhino currently featured on the Cincinnati Zoo homepage.
