Parent: Honey it's David Tennant-thirty you need to go to bed.
Child: But mom! It's not even a school night. I want to stay up past Peter Capaldi for once.
Parent: You can't, you have that doctors appointment at Christopher Eccleston tomorrow morning.
Child: How about Matt Smith thirty?
Parent: Fine but if you miss your alarm at Paul McGann I'm not rescheduling for you.
