most of the jokes in there don?t require responses?
Most of the jokes are so old they can't hear responses. 
Welcome in young Marley. Has the "buy Darwin a large malt" tradition been explained to you?
No it hasn't; is it anything like the "Welcome Marley, here's a generous snifter to lubricate your whistle" custom? If so, I'll stand you one if you'll stand me one.
O.K.?
OK, you first 
No, after you - you are the local and regular so by rights you should be in the chair (only chair I'm likely to be in is a bath chair the way my back is today)
Of course dear boy, where are my manners?
Barman, my usual please and a half of shandy for Mr Ghost.
