LOLOL: Girl Accidentally Locks Her Phone In Timed Phone Jail For Two Days

This is a video of a girl whose brother put her phone in their dad’s new phone jail (just what every dad wants. Actually this $70 Kitchen Safe locking container), then the girl unknowingly spins the dial on top (what’s this do?!), increasing the lock time to 2 days, 3 hours and 40 minutes. Then she starts laughing and crying simultaneously. Haha! *sobbing* I do that all the time myself.
