Susan & Zac met when they were both enrolled in The Second City's conservatory program studying the storied arts of improvisational & sketch comedy. They didn't know this then, but apparently, it's also a matchmaking service. They can be seen below performing in the sketch they wrote together entitled, "Allergies." It was a satirical look at all the ridiculous allergies people claim to have in this day and age. It was "funny." So funny in fact, at one point during the scene, Zac acts as though he slams his head on the chair he is sitting on. This particular time though, he really hit his head on the chair, creating quite a gasp from the audience. Later discovering backstage that he hit his head so hard, it was now bleeding. Remember, as it was stated earlier, it was "funny."
