I live in a 115-year-old house. I’m always telling the kids to stop hanging on the doorknobs. “Those doorknobs have been around 115 years and you guys are not going to be the ones to break them!” At least they aren’t knocking the beard off Tut’s mask.

4 minute clip from “The Social Network” (how Facebook got invented). It’s amusing scene, featuring a portrayal of Harvard President Larry Summers, and it mentions old door knobs. Clever dialogue.
