17166 Secombe           Discovered 1999 June 17 by J. Broughton at Reedy Creek Observatory.
Welshman Harry Secombe (1921-2001) was the chuckling roly-poly singer-actor-comedian "Neddy Seagoon" of The Goon Show fame. On receiving a knighthood he referred to himself as "Sir Cumference". Secombe was a unique combination of comedian with a magnificent tenor singing voice.
