Cut and pasted from one I just came up with on an autie forum I haunt, for context, the thread was obvious humor that nobody gets, because they read it as normal, without analysing it, and crossings for the blind came up 'how do the blind people know where to cross'
And I came up with this new one, if you like cruelty to disabled people, and who doesn't eh? you might like this:
My theory about the blind cross signs, is there must be some standard depth of ditch, where Q is the quantity of water present, V is the velocity of the approaching vehicle, B the quantity of blind people present at any one puddle spot in any one time, and A(anger) how damn cross said blind people get when vehicle passes by at speed, hitting puddle on the way thus Q*V=BA=proportional amount of anger experienced by a given amount of blind people waiting at the crossing, when hit by filthy muddy water, driven faceward by a vehicle of a given velocity.
I know someone, a member of staff from my old boarding special school that used to take great delight in doing this, not to blind people, but just anybody that happened to be between a puddle and a speeding minibus going down country lanes, certainly not funny having it happen to you, and boy does it ever make one a cunt to delight in it, but we did, at the time
