I was doing ok until I got the the part about dumping down the sewer.
Undertaker: Yea. Now there’s three things we can do with your mum. We can bury her, burn her, or dump her.
Man: Dump her?
Undertaker: Dump her in the Thames.
Man: What?
Undertaker: Oh, did you like her?
Man: Yes!
Undertaker: Oh well, we won’t dump her, then. Well, what do you think: burn her, or bury her?
Man: Um, well, um, which would you recommend?
Undertaker: Well they’re both nasty. If we burn her, she gets stuffed in the flames, crackle, crackle, crackle, which is a bit of a shock if she’s not quite dead. But quick. And then you get a box of ashes, which you can pretend are hers.
