Don't bet the real superbowl, bet the old one.
Record old superbowl between Giants and Pats. Have a friend invite a bunch of English as a Second Language student over to their dorm. Watch the game. When the Giants are losing, say, "I bet $100 that the Giants are going to win!" Collect cash--many of these kids are rich. There you go...free tip to make some money...might have to bet whatever amount these students will have on hand...so plan accordingly. Do a monopoly set up... 2 $100 bills, 2 $50 bills, 5 $20 bills 10 $10 bills, and 10 $5 bills, and maybe $20 1's. Maybe, even do a losing prop to get their gambling blood running, before collecting big. Good luck and let me know how it goes.
Ignore the above: just watch the Superbowl. I failed!
