Do not hire this plumber
This is excellent stuff. Very funny, well written/improvised and executed. He plays the part well and it reminded me of The Office atmosphere where the comedy can be from the silences as much as the dialogue. He also reminds me of a Paul Kaye creation.
Asking for a bag of peas is laugh out loud funny 
Wanted to bump this because it has some very funny moments. Also check out the other video on youtube by the same author. The drunk acting by the girl in that is the best drunk acting I've ever seen. She makes it totally believable.
