My oldest son, Kimbo, has an interesting sense of humour.
Many years back, he asked his younger brother, Wills, to sit for a portrait. Wills was too busy, and said 'NO'.
Kimbo (who must have been about 15 at the time) began to draw him anyway, and in an attempt to frustrate his attempts Wills sat shaking his head from side to side, saying 'don't draw me, don't draw me!'.
Above is the result.
The tiny 2 by 3 inch drawing hangs just beside where I'm now writing, and it makes me smile every time I look at it.
