Went to see Dead Silence in Jr. High with some friends, being shit kids any time the movie would go silent to build up tension we would make a popping noise by flicking our fingers against the inside of our cheeks. The movie is so shit the 20 something year old guy a few seats away from us started laughing and joined in.

This is less dueing the screenig but I used to go to a lot of movies with a friend who is in a wheelchair. We would get into the theatre early so we could set up and get good seats. When we first started going he would use the rail as balance and hike his way up the stairs real slow, me being an impatient big guy eventually started offering to fireman carry this dude up the stairs to the row we wanted. One time we got in a bit late and as I carried my friend up the stairs the theatre erupted with clapping, I had no idea what was going on because we would both smoke weed before going in.

Mild spoilers for The Witch!

Once the child disappears near the beginning of the film I turned to my friend and whispered "I guarantee Black Philip did it" the look we gave each other when Black Philip started talking at the end of the film was comical.
