Big feet

I was hanging out with my friends and my one of them said something about his shoe size so I said, "you know what they say about big shoes" and as soon as I said that, my mother was glaring at me from around the corner

Once I went shopping with my mum and found some slippers to buy for a friend. I called him and asked him for his shoe size, then got a REALLY dodgy look from my mum who loudly announced what I had done to the shop, innuendos included. When I told my friend I found out that his dad had done the same.
