Not just visual puns, musical puns too in the song that was on gromit radio.

I also like the spread on the table in the kitchen at the begining.
The Name of the pest company
The sticker on the cheese box that gets wore by a certian chatrter.
Of course the hair,hare, type jokes.
and the bunnys where cute :)

Ok is that veg enough so it doesn't spoil movie but no so that you can't remember and laugh?
