Oh, no need to worry about this group of boys.
They also played 'sneak up on the earth moving machines' that
were working in field next to us.
I banned 'can you skate board behind a moving car'.
I dressed wounds from 'can you juggle axes' (not really well).

And that was just the stuff I knew about....

They were much safer after they turned their energies
into becoming the next big punk rock band (and even
wore the ear plugs I bought them) though I think our
house settled about five inches from the resulting musical mayhem.
