treatise on kicking doors open

i have very very powerful legs and i don't know if they will ever be put to use in the way i'd like to use them. i mean - i'd like to kick a door open and say "GET THOSE MOTHERFUCKIN HANDS UP!" see below for an example:

mostly in non-combat related, friendly situations where like, i just want to use the bathroom and its occupied.
that friendly situation probably would turn unfriendly very quickly, but it would be very very very funny.
