In the "Big Gino" episode, Sid had a camera because he had to give Arnold a swirly and take a picture. He had the camera with him because he was going to ask if it was okay with Arnold. But the mistake is yet to come. He was so shocked when Arnold came- He clicked the button to take a picture because the flask went, but no film came out. There had to be film in the camera because He was supposed to do the swirly that day to Arnold.
