A swan rescued me from an evil goose that was trying to mug me in St James Park, I had run out of bread to feed them and the bastard goose snatched my toy cat, Midnight, out my hand and waddled off with it til Super Swan attacked the goose, making him drop Midnight, then chased him off.
Midnight was covered in crumbs and half eaten quavers, probably some ice cream/icing, maybe some half chewed sweets, as all toddlers toys are on a picnic with Grandma so they were probably fighting over about a weeks worth of food hidden in her fur but poor Midnights ear was hanging off.
Point is, its not the swans with teeth you want to worry about, its the damn geese!
