So remember how Ten got his hand cut off in The Christmas Invasion? And then he grew a new hand?
Well, that hand is slightly newer than the rest of his body, so when he regenerated, that hand still had some of the Doctor’s Tenth regeneration in it, and occasionally it reminds the Eleventh Doctor of that fact. It does this by doing things like letting Eleven know when he’s being stupid. As seen here:
The premise of minimum wage, when it was introduced, was that a single wage earner should be able to own a home and support a family. That was what it was based on; a full time job, any job, should be able to accomplish this.
The fact people scoff at this idea if presented nowadays, as though the people that ring up your groceries or hand you your burgers don’t deserve the luxury of a home and a family, is disgusting.
