"First came Jermaine Jr, then Autumn, then Dawn. Jeremy soon followed, as did Jaimy and Jourdyn. Six children might be enough for most fathers, but not Jermaine, who soon was welcoming Jaffar to the family. Jermaine then took his child-naming abilities to new heights, christening the next arrival Jermajesty.
Such heights must have had an effect on Jermaine as for his ninth child he broke from his alliterative tradition to name him … Dave. Thankfully, tradition was not long broken as baby Jesus arrived in this world. Jesus Jackson, that is." (wikipedia fount of all knowledge confirms this)
Why didn't he put any Tube station names in there? Admittedly none begin with the letter J, but there are lots of lovely unusual first names he could have chosen from his favourite line - Fairlop, Debden, Hainault, Leyton & Snaresbrook. They all have a rather exotic ring to them and certainly beat Dave if you're going to break from tradition.
