Night of The Hill Jacks! Plus Question

Hello again, Poppa Smark! Since you've been so kind to us in the past, we were curious if you would indulge us once more with a plug for our newest wrestling-related podcast! I recently attended a WWE house show in Springfield Illinois and literally have never seen so many Hill-jacks in one place. I say this as someone who wrestled independently for years and has attended WWE shows in more states than I should be proud of. Both of us are comedians and we have fun with our judgemental rants on the episode! Who's the most interesting fella you've seen at a wrasslin' show?
