Dig This (S04E30)

Mr Bean attempts to build a shady gazebo in the back garden on a scorching hot day. But as he digs into the ground he unearths a huge unexploded bomb. Trying to make Mrs Wicket aware of the danger, and save Scrapper and Teddy from being blown to smithereens, takes courage, nerve, and a Bean styled homemade bomb disposal kit. (iTunes)
