Celebrities help at Cantor Fitzgerald's charity day

Supermodels, actors, athletes, rappers -- just about everyone you can think of turns out for the annual charity day at Cantor Fitzgerald. They donate their time to help the company raise money for more than 100 charities around the world. Since 9/11, charity day has raised more than $100 million.

Celebrities hit the trading floor and make trades. Actress Edie Falco and actor Steve Buscemi worked the phones. This is the 4th year that rapper 50 Cent has donated his time.

Cantor employees donate their salaries and commissions for the day and the company donates $100 percent of its revenues to the Cantor Fitzgerald Relief Fund. The money is then distributed to charities.

Cantor Fitzgerald lost 658 employees on 9/11. Edie Lutnick is the executive director of the relief fund. She lost her brother, Gary.

What keeps these folks coming to charity day: making a difference.
