Cannon Penis

Cannon Penis is a catchphrase derived from Smosh 2nd Channel (at the time IanH) series Ian is Bored (now Smosh is Bored) (Episode 27), Cannon Penis involves taking a popular image of Ian Hecox standing behind a cannon as if it were his penis, and applying it at certain points in a video to create a quite possibly awkward, or comical, moment.

Trivia

 * The cannon is at a mini golf course.
