Service members were left in stitches thanks to three comedians from The Comedy Corps, who performed in the New Cantina, Aug. 23, at Camp Lemonier. PJ Walsh, pictured above, is currently performing with the "Blue Collar Comedy Tour" and has a military background. He enlisted in the Navy a few days after graduating from high school and was tapped to serve as the primary dental care technician for the White House, during the Clinton years.
