Same thing happened to me with my neighbor. I wouldn't call him old, he's 50, but yeah. Here's how it went;
Me: Guys, get out of the road Mr. ******** is driving by.
(I walk on the nearby snowbank)
Him: WHAT DO YOU THINK YOU'RE DOIN'?
Me: Wut?
Him: DON'T RUIN THOSE NICE SHOES YOU GOT THERE BY WALKING ON SNOW!
Me: Ok.
Him: MUHAHAHAHAHAHAAHAH.
Me: Ok sir. Have a nice day.
He seriously laughed like that. And he drove away while laughing. Creepy folk.
