Honored by Comedy Central as one of the Top 100 Greatest Stand-ups of all time, Griffin often tackles organized religion in his routines (he's a major and vocal opponent). In his comedy special You Can Tell 'Em I Said It, he spouts, ''I think Christians are jealous of Muslims, because you are not going to out-devout a Muslim. That's the most devout faith you'll ever run into. A Muslim will strap a bomb on himself and blow himself up about some Mohammed. Ask a Christian to strap a bomb on him and blow himself up about Jesus. 'No, he wouldn't want me to do that. He just blessed me with this house. I'm sure he wants me to live in it.'''
