I was out and about and visited a local garden centre.
There were concrete ones in buff, cream and grey, as well as ceramic glazed ones in blue and black.
Now it makes me think of Matt Smith!
The connection was referred to in The Impossible Astronaut, when The Doctor and River Song are syncing diaries. They mention Easter Island, alluding to the visual resemblance between Matt Smith and the famous statues.
“The TARDIS has been whirling charmingly in space since the pre-Nando’s era, and in that time it’s housed 11 Doctors: Silver-haired grandpa William Hartnell; flute-playing hobo Patrick Troughton; dandy Worzel Gummidge-in-Waiting Jon Pertwee; eccentric boggle-eyed mop Tom Baker; Peter Davison, the troubled-looking Timotay Doctor; Colin Baker, a permed and spiky weirdo; kooky walking tour guide Sylvester McCoy; tousle-haired motorbiking action hero Paul McGann; crop-haired and intense Christopher Eccleston; national crush David Tennant; and the new guy, Matt Smith, who looks a bit like a friendly Easter Island statue in a bowtie.”
