"I've got a new job..." Jokes

This is how we have spent the weekend. Making up "I've got a new job..." jokes. Have you come across this idea yet?

It's a simple idea. The jokes have a common format of question and response format - a bit like knock-knock jokes. Also, like knock-knock jokes there seems to be an almost infinite variety of responses and puns are often at the root of the humour (assuming you find the concept humorous).

The baseline joke, the one that defined it for us and sets the standard that the other jokes will hopefully exceed, is as follows:

Person 1: I've got a new job.
Person 2: What is it?
Person 1: I'm a dustman.
Person 2: How's that going for you?
Person 1: It's rubbish!

See how it works? Some of our favourites so far are:

Person 1: I've got a new job.
Person 2: What is it?
Person 1: I'm a tailor.
Person 2: How's that going for you?
Person 1: So-so.

Person 1: I've got a new job.
Person 2: What is it?
Person 1: I work in a laundry.
Person 2: How's that going for you?
Person 1: I'm cleaning up.

Person 1: I've got a new job.
Person 2: What is it?
Person 1: I'm a miner.
Person 2: How's that going for you?
Person 1: It's the pits!

Surely you can do better than that. Leave your New Job jokes in a comment and a special Perrier no-prize will be awarded to the best.
