Mayor Bloomberg signed one last controversial bill into law before handing over the reins to Mayor-elect Bill de Blasio on Jan. 1. Bloomberg signed a bill on Monday banning the use of e-cigarettes indoors.

The New York Daily News reports that Bloomberg actually signed 22 bills into law on Monday, bringing his total to 833 during his 12 years as the Mayor of NYC. Bloomberg also signed into law a ban on Styrofoam. However, according to the Daily News, it was the renaming of six city streets that will go down as Bloomberg's last bill as mayor.
