In the barbers last week I heard someone say 'That randy old Cat-Flap!' about a bloke in town. Cat-Flap = Bisexual because they swing both ways.

I read your post with much anticipation.

Which is also excellent for 'planting' fence posts in.

Concrete a section of gas pipe about 16 inches long into the ground and plant the 4 inch or whatever fence post into it surrounded by pea shingle.

When post rots away, just lift it out and drop another one in.
