I was doing my paper round once and i was walking up a hill when I slipped on a huge piece of ice and I kinda rolled down the hill with my newspapers going freaking everywhere.
I get up to see some old women at the bottom of the road laughing her head off like she was going to collapse. She actually stood there and watched for 10 minutes whilst I located my newspapers (laughing all the while).
Possibly one of the most awkward moments in my life was having to walk past her back down the hill *sighs*
So basically what I do when I fall over is laugh it off, usually I try and walk away from the witnesses as fast as I can without looking strange
