Never bought a bike and forgot about it, but one week Aldi had those handy little sanders which fit in the palm of your hand, so I thought "That looks handy - I'll get one of those".
You guessed it - went to put it in the garage, and sat it on the shelf next to the other one I'd bought the previous time they'd had them in.
The missus blamed my age, and that I buy most of the tools Aldi have going.
Fortunately, it was just before my brother's birthday, so he got an unexpected present as well as the usual funny card.
