Over the Hedge: Hammy Goes Nuts!
Plot synopsis: Hampster thing or possibly a red squirell that actually looks brown for some unknown reason loses it upon waking up one fine sunny morning only to find he's expertly managed to completely dislocate his jaw during a particularly explict dream involving nuts. Thus begins a heartwarming tale about denial where Hammy quite literally runs around the world attempting to avoid the clutches of the local vet. But he's not alone, as a proverbial mountain of animal welfare campaigners are close behind, out to thwart his quest to evade a session on the operating table. The whole point being that Hammy really is completely utterly and totally insane, for having kept up-to-date with payments on his health insurance he's really got nothing to worry about, and a spell in the vetinary clinic might actually do him some good.
Moral of the story: Commmunication, people!
