Today (May 8) the celebrities got philosophical, talked temperature, prepped for dental work, figured out Twitter, visited old stomping grounds and acted as human calandars.

Donnie Wahlberg figured out what day it was.

LeVar Burton got pretty deep on everyone.

 

Former Dresden Dolls frontwoman Amanda Palmer was also trying to philosophize.

 

And of course Chris Brown made some little girls in Harlem cry.
