Uh, I do a lot of silly stuff but I guess... I spent hours, days worth of hours, practicing an elaborate proposal for my ex that involved lip syncing, Disney songs and my cousin releasing doves, which I then chucked out the window - the plan, not the doves - like a week before we were gonna do it for some impulsive proposal.

Freakiest was maybe hiding under a dead body during an operation when things went bad and then stealing the guy's uniform. I don't know if that's weird, but I was freaked out at the time, so I guess it counts.
