Never is the title of you dirty old man more deserved then in this episode. It's hard to believe nowadays that many people used to bath this way, but it's the manner in which he bathes, complete with pickled onions, that's particularly dirty.
The two characters are polar opposites, despite being father and son, Albert a bit common, Harold with ideas. The thought of walking into someone's living room, and seeing someone in a tin bath, hard to imagine.
Harold is a little selfish once again, as he moves his old dad into the cupboard under the stairs. Some great lines, including Albert's retaliation at being moved, and a funny scene where Harold's second date discovers the old man.
Yootha Joyce, very funny as Delilah, she would appear in two more.
Very funny. 8/10
