My cousin and I were particularly destructive children and used to build paper airplanes and fly them up into the ceiling fan. Sometimes they'd get caught on a blade and come flying off. Was playing a lot of Starfox 64 at the time, so we imagined we were attacking a boss. We'd try and see how many attacks we could get in before our plane was completely mangled and wouldn't fly anymore. Good times.

Another destructive game we used to play was lighting army men on fire and fusing their melted plastic bodies together to create a zombie army of plastic amalgamations. Half-green, half-tan grenadiers with bazookas for a heads, etc. God bless America!
