H: [after making some strange face or sound or both] Oh Brad, why am I so weird?
B: I stopped asking that a long time ago.
H: Oh come on, you've met my dad, you're supposed to know the answer to this.
B: Oh right! It's genetic! ... I get my bad sense of humour from my dad.
H: What?!? You've got a fantastic sense of humour!
B: Yeah! I don't know where I got the good part from!
