Isn't it funny how "clever" people don't seem so good with practical things?
My mrs is doing a b.a. hons at uni, the other day I got her peeling spuds for sunday dinner (I normally do all the cooking because I know she's hopeless at it but my thumb had only just been bandaged), anyway, I gave her the peeler and left her to it while I popped to the shop for some vegi oil for the yorkshires.
When I got back, I noticed she looked a bit sheepish. On further inspection, she was trying to peel the tates with a (very sharp) 9" carving knife!! And the tates were all kinda square

it was so rediculous I couldn't believe my eyes, had to laugh though.
