Well, everyone knows a TARDIS is bigger on the inside!
Until I saw this tweet yesterday, I did not realize that TARDIS fridges were a thing. Apparently they are. The internet is full of them. Or full of a few, at least. ThinkGeek makes a TARDIS minifridge, but I’m frankly far less impressed by this professionally-made product than the homebrew options. Some of them are just so cool!
So now you know: In addition to the many other things out there masquerading as TARDISes (and there are many), your fridge can join the action, too.
