"I think coffee is the one constant in the multiverse."
"They are called Swedish meatballs.
It's a strange thing,
but every sentient race has its own version of these Swedish meatballs!
I suspect it's one of those great universal mysteries
which will either never be explained,
or which would drive you mad if you ever learned the truth."
It's a dream of mine that one day, Swedish meatballs will be mentioned in some way on 'Doctor Who'. No big deal has to made of the reference, but it would be enough to show that both series has this trivial connection.....
