There is a scene in a popular movie where a group of women are getting together for a girls’ night and a guy is teaching them how to give blow jobs using vegetables. The man/husband comes in and punches the instructor. This had me cracking up, but I can’t remember which movie it was from.
Old school, starring Will Ferrel.
And it’s Andy Dick giving the BJ lessons.
Life Imitating Art? 
I’m not entirely sure that Andy Dick even knew that they were filming a scene.
