Looking for an episode with bird on a teapot

uy fans!

Looking for an episode I saw a long time ago... The scene I remeber — and the reason I'd like to watch it again is :
at the end of the episode, in the farmer's kitchen, Shaun (or is it Bitzer? sorry!) places a bird onto a teapot in order to replace the missing teapot's lid.
And the bird smiles with all its teeth at the farmer (that image was really hilarious)..

If anyone could help, I'd be so grateful!
