Gene Simmons of the rock group KISS was a special guest on Wednesday night's Halloween episode of Jeopardy.  In full KISS costume, he hosted the category "Halloween with Gene Simmons".

And Jeopardy host Alex Trebek couldn't resist getting into the act too.  At the end of the show Trebek was shown in full Gene Simmons regalia;  costume, make-up, wild Gene Simmons hair and high heel boots.  What a scream.  And full marks to Trebek for playing along with it.  It looked like both Simmons and Trebek were having a ball.
