With the big day coming soon for the 50th anniversary episode of Dr. Who, the BBC has been releasing all kinds of tidbits to whet fans appetites. The Night Of the Doctor is a terrific 7 minutes of Dr. Who aperitif but the 12 second teaser found below will make you grin like a Cheshire Cat. Steven Moffat has said that fans are in for the, “best ever entrance” into the Tardis, and with this teaser we can only assume that this is it. To truly find out though, you’ll have to watch The Day of The Doctor this Saturday 11/23/2013.
