10 Doctor Who Episodes You Didn’t Know Were Connected

10. Silver Nemesis & The Big Bang

The Eleventh Doctor's unorthodox dress sense inspired a generation of teenagers to think they were cool because they owned a tweed jacket.

Not only did bow tie sales shoot up when Matt Smith started wearing one, but his version of the Time Lord also inspired a fascination with a certain red hat.

Number Eleven first appeared in a fez in the Series 5 finale The Big Bang. The headpiece would turn up throughout the rest of his time on the show, becoming a trademark of Smith's quirky portrayal of the character.

But this was not the first time the Doctor had been seen in one.

In Doctor Who's 25th anniversary special Silver Nemesis, the Seventh Doctor and his companion Ace turn up at Windsor castle and have a rummage around, and at one point, the Doctor pops up holding a mop, and wearing - you guessed it - a fez.

Considering that Eleven was also holding a mop when he was first seen with a fez, we can deduce that this moment is where he got the inspiration to wear one on the regular.

Not a massive detail, but a fun one.
