On the set of Stargate SG-1 it was an in-joke that Martin Wood (director) and Dan Shea (stunt coordinator) would often walk around with oversized wrenches in the background appearing to do work. In the season 5 episode "Red Sky" they both appear.
Since I'm aware of this now, I keep noticing them in new places on every rewatch!

All the years #stargatesg1 was running and not once did anyone go through the gate, pause on the other side, forget what they were doing there and then dial back home.
It'd be a weekly occurrence for me.
