Why Is It...

[cupid04]

Whenever you run a tap you want a wee?

Or when you've got your hands in a bowl of washing up you get an itch?

Mr. c says it's sods law.

Have you got any other instances?

[stuey]

When you're disassembling something held together with screws and/or nuts and bolts, one of them will give you problems: it'll snap off, or it's frozen in place etc?!

Go to the loo and the phone rings!
