Greg saw a dog dying in a 100+ degree car one day with window open just few inches, the police wouldn't come out, and I was running out of time, and so instead of busting out the guys windows and facing possible crime charges, I went into the garage, grabbed my shop vac, stuck it in to my car with the AC on full blast and stuck the hose on the discharge port and shoved it into the guys car window.
It turns out that the guy ran into his dad's house and found him stroking out on his kitchen floor, called the EMT and in his freaked out panicked stage he strode with the ambulance to the hospital and forgot about his buddy sitting in his truck.
Finally when you came back, (within in an a hour), he broke down in tears when he saw my rig running and his dog wagging his tail inside his vehicle. All ended well with dog and dad, and to this day the guy and I (and the dog) are all good friends.
