So what custom rules do you submit your mates to when they pop round for a spot of backyard cricket / baseball?
Is it the standard "one hand one bounce"? Over the fence is Six / Home run and Out? Do sisters with teh hotness get three outs (9 strikes i guess

).
At my house we have:
Dog catches the ball on the full, out
A hat trick (3 outs) gets you and extra life when batting
If it hits the clothes line on the full its four runs
Kids under 10 get an extra life
taking a catch launching from the trampoline or into the pool (clothed) scores a free beer
