Some-thing to get the more creative amongst you going. Let's see some football chants with a few comedy "errors" or "mispronounciations" in them. Here's one that tickled me a bit when I though about it. Imagine Porky Pig and Arkwright from Open All Hours as Pompey fans.... Per per per per Play Up Per per per per Pompey Per per per per Pompey Per per per per Play Up! I'm sure you can do better than that!
Here's one I thought of for that "popular" ex Pompey player, Michael Brown...now appropriately plying his trade at Dirty Leeds. When he's around, better watch you backs, He's bad tempered, full of ire, He'll chop you down like a dead old tree, Dirty old Brown Dirty old Brown (To the tune of the Pogues classic "Dirty old town")
