What can you say? What happens doesn't always seem immediately funny to the listener, particularly if you do not know the nth degree detail of cricket, but what so clearly comes through is that it is funny. And that the brodcasters, not least of all Jonners, cannot stop themselves and therefore nor can you. You just get carried along on a wave of uninhibited almost boy-ish enthusiasm and love for their sport. Things which to a non-English person may well seem at least utterly peculiar if not downright bizarre.
