A perch, a roach, and a dace went into a bait shop. 'Can we have a can of worms please ?' asked the roach. 'This is a bait shop' said the shopkeeper, 'it says so outside. We don't serve fish'. 'Not even a can of worms ?' said the carp. 'No, it's a bait shop' said the shopkeeper, 'it's as clear as a bell on the sign outside, now clear off'. 'Oooooh who's falling off his perch !' said the dace.
