YEP !! Ive done it one minute there i was !! then the next moment my knee cap was in my chest with my other leg down the hole and my arms outstretched either side of the hole,

no damage to me the manhole cover f.u.b.a.r.ed and my mate in a puddle of his own pee and tears laughing so much he couldnt get me out!
I love the different things that we face on a daily round!! Tom
