Len once joked he wanted to settle down with Bruno Tonioli since he was a good cook and ironer.
Len was sixty when he was first asked to appear on Strictly Come Dancing.
Whilst Len was filming Dancing With The Stars in America for seven weeks, he got incredibly homesick, saying, "I was pleased when it was all over."
The lowest score he has ever given on Strictly Come Dancing was to Quentin WIlson for his Cha Cha Cha in series two.
He has judged both the British and the World Championships.
Len specialises in Exhibition dancing, which is similar to ballroom dancing, but involves lifts.
Len once described himself as "the star that never twinkled."
Len only made his way into ballroom dancing after he broke his foot playing football. His doctor suggested either swimming or dancing and he did not know where his nearest swimming pool was so he turned to dancing instead.
Len (to Anne Robinson): Go on. Get your dress off.
Len (on Strictly Come Dancing): This is the icing on the cake.
Len (on being recognised): People are never nasty to me because they think I'm the kind judge.
Len (on fame): It's nice to be recognised.
Len: I know I come out with a lot of funny comments and analogies sometimes about sausage and sizzle and all that.
Len (on dancing): If the footwork's good, you can build on the choreography, but if it's not there, then it's like building a house without strong foundations - the walls are going to fall down.
Len (on Strictly Come Dancing): We get a lot of flak from audiences who think we're being mean to their favourite celebrity, but I have to keep stressing that we're voting with our heads. It's up to the audience to vote with their hearts.
Len (on Will): He's not willowly - because his name's Will.
Len: The tango is like a pickled onion.
Len: Ooh, scary eyes.
Len: Turn your trunk so our trunks are touching.
Len (on Camilla) Didn't she crumble beautifully?
Len (on judging dances): It's like brussel sprouts. You might like them, I don't. Neither of us is wrong - it's a difference of opinion.
