In my acute mind I can see a man (Satya Nadella) standing in a desert. With no socks and shoes on. Aiming a rather large 12 bore shotgun at his foot. Then! a loud bang, The man looks down and half his foot is missing.
I think shooting yourself in the foot is something you would do to avoid drafting. It makes me sad that this may become relevant again in Europe. It certainly is in Ukraine and Russia. : (
Also include a loud scream as the man sees his foot is gone, And shouts "Where's my foot?! What happened to me???", being absolutely dumbfounded by this observation.
