Dennis has moved into teaching!
If you like It's Always Sunny...you'll like this, its very funny.
Dennis's, sorry, Jack's nemesis Is a really unfunny Ricky Gervais impressionist (if you think RG isn't funny then you're wrong) but proves for obvious and funny scenes.
The cast are brilliant especially Patton Oswald and Allisyn Snider but I'll say it again, Dennis from Sunny has a teaching job. It's everything you'd expect from him.
