Wonky Leg Fixer

I was not sat at my usual desk today and was faced with using a keyboard with wonky legs. It's so annoying having a keyboard that's not stationary.

I solved the problem by putting one of these rubber things from the stationery cupboard over the offending leg.

I haven't a clue what these things are called but its a size 12 and made in China.

I think I have the post-holiday blues and chocolate won't do! :(
