Jas = Jack, Jackie
Probably, the Rowland Atkinson character represents the English Everyman, the ordinary bumbler, much like Doodles Weaver or especially Lucille Ball ("ILove Lucy" etc..) here in the States.
Thanks for the Jack explanation.
You mean like John Doe? No, he's not called Mr Bean for that reason in the UK, where the programme originates from.
From Wikipedia:
The title character, played by Rowan Atkinson, is a childish and selfish buffoon who brings various unusual schemes and contrivances to everyday tasks. He lives alone in his small flat in Highbury, and is almost always seen in his trademark tweed jacket and a skinny red tie. He also usually wears a digital calculator watch. Mr. Bean rarely speaks, and when he does, it is generally only a few mumbled words which are in a comically low-pitched voice..[13]
Mr. Bean often seems unaware of basic aspects of the way the world works, and the programme usually features his attempts at what would normally be considered simple tasks, such as going swimming, using a television set, redecorating or going to church. The humour largely comes from his original (and often absurd) solutions to problems and his total disregard for others when solving them, his pettiness, and occasional malevolence.Sounds like a character based on something it should not be based on at all.
The utterly unfunny Mr. Bean
+1 Although he has laughed all the way to the bank, big time.
