TONY HO, the four-time Canadian Comedy Award nominees and all-time kings of dark, disturbing sketch comedy released a new video today called Dissection, co-starring Allison Hogg of The Sketchersons and directed by Dan Beirne.

We’re telling you this to encourage you to watch it but BE WARNED that it might cause funny nightmares like that one you had when you were a teen where your family lived in a jockstrap but no one really cared.

The sketch follows three medical students who gather together to make up the human dissection class they all happened to miss. What begins as a standard anatomy lessons turns into something much more sinister once the professor—played by a menacing Miguel Rivas—reveals dark secrets.
