When I was in third grade I asked my teacher for some extravagance like an ice cream party. The teacher said "You'll get your ice cream party when pigs fly". My mom was also a teacher so I hung out around the school once the kids left.

I cooked up a plan with the head custodian which included drawing a pig with wings on paper twice, stapling the two pigs together with cotton balls stuffed inside and coloring it pink. Then Melvin and I hung the flying pig from a long piece of twine taped to the side, GOT ON THE ROOF OF THE BUILDING, and swung the pig back and forth in front of my teacher's window.

She correctly concluded that pigs had flown, our ice cream party was arranged and Melvin got the first bowl. He retired as a much loved member of the community and I get to remember that here was a time like 40 years ago when some adults would help kids do cool shit.
