That's a lot of Doctors. Plus I've got the Ninth/Tenth FC Tardis, the Eleventh FC Tardis (which is just a bloody repaint so I don't know why they were to cheap to include the interior lights...) so that's five versions of the Tardis and the Ninth/Tenth playset.
And then there's my Dalek collection and my classic Cybermen collection and the various monsters from the two classic waves and my various new series figures and... a rough tally means... I've got far too many toys.
The, is it possible we're all just obsessed with recapturing our childhoods? Or are we just geeks?
