A new PSA for Cyndi Lauper's Give a Damn Campaign debuted Monday night, in hopes of eliminating instances of anti-gay bullying in the wake of incidents such as last week's suicide by a Rutgers college freshman after classmates outed him.

Elton John, Idina Menzel, Rachael Harris, Wanda Sykes and Ricky Martin -- in one of his first appearances since coming out earlier this year -- all are featured in the clip, which was shown on Monday's Larry King Live.
