I have zero guilt in my pleasures.
But, if I had to play to play along...
I enjoy watching compilations on YouTube of epic fails. Nothing painful or gutwrenching, rather in the vein of really bad auditions. I prefer watching people who think they can sing, but can't sing a lick or are incredibly tonedeaf.
Then Simon Cowell says something like, "Who told you can sing?" after the horrific audition. To which the contestant retorts, "Everyone! Even people who don't like me tell I can sing."
That's often when you can find me on the floor, dead from laughing so hard.
Sometimes, I feel bad/guilty for laughing but, it's the delusion that sends me over the edge.
