2. My brother doesn't miss a when it comes to making money.
3. A little bit of glue will do the and your teapot will be as good as ever, Mum.

I think the answer is

1. Will you teach me that card JOB, Joey?

2. My brother doesn’t miss a JOB when it comes to making money

3. A little but of glue will do the JOB and your teapot will be as good as ever, Mum.

The quote from animal farm is “four legs good, two legs bad.” This expression, which happens in Chapter III, establishes Snowball’s compression of the Seven Commandments of Animalism, which themselves function as condensations of Old major’s inspiring speech on the need for animal harmony in the face of human domination. The phrase requests one of the novel’s many moments of propagandizing, which Orwell depicts as one instance of how the top class misuses language to govern the minor classes.
