So many possibilities & ways to settle in & enjoy the 'Day Of the Doctor' on this one & only occasion. Here's a few ideas, but which ones will you be following:
[LIST=1][*]In 3D at the cinema;[*]In HD in the comfort of your home TV;[*]Wear a ridiculously long scarf in homage to Tom Baker's Fourth Doctor;[*]Or, celebrate the Eleventh Doctor far more given that it's his tenure that is coming to a close . Wear a fez & a bowtie and feast on Fish Fingers and custard (which, personally, I can highly recommend! );[*]Buy a Doctor Who souvenir/memento like a compilation book of the last 50 years or a Tardis teapot or replica of the Doc's sonic screwdriver (BTW I'm not trying to hawk my wares like some Internet spiv!);[*]Go all in on the Tenth Doctor with a long swishing coat & midnight blue suit to celebrate David Tennant's inclusion in the special;[*]Re-watch the special numerous times, at least until the Christmas regeneration of Matt's Doctor;[*]For the ladies (and others ), wear a sexy red dress akin to Oswin in 'Asylum of the Daleks'. [/LIST]

I'm just spit-balling a few ideas out here, but any more suggestions?
