It's not so much a cool thing I did on a call, but just the calls itself were cool.
I had an elderly male (about 83 years old) die of natural causes. I arrived on scene and basically was just there to comfort the family, because we got the pt's family doctor to sign the death certificate. The family was all gathered there.
Fast forward 4 months later, I get dispatched to a pregnant woman currently in labor. She was parked in a gas station, so I was able to get her in my cot and in the back of my rig... and delivered the baby right there at Speedway She said I looked familar to her, and then it hit her. That was her grandfather that passed away, and I arrived on that scene. I was there when her grandfather left this earth, and I was there when her child was brought into this world. Pretty cool!
Also... I got the sign the birth certificate on that baby too
