:) Groovy - and it works for the edge cases too...

irb(main):033:0> a=[1,2,3]
=> [1, 2, 3]
irb(main):034:0> a.join(', ').sub(/, (\S+)$/,' and \1')
=> "1, 2 and 3"
irb(main):035:0> a=[1,2]
=> [1, 2]
irb(main):036:0> a.join(', ').sub(/, (\S+)$/,' and \1')
=> "1 and 2"
irb(main):037:0> a=[1]
=> [1]
irb(main):038:0> a.join(', ').sub(/, (\S+)$/,' and \1')
=> "1"
irb(main):039:0> a=[]
=> []
irb(main):040:0> a.join(', ').sub(/, (\S+)$/,' and \1')
=> ""

Thanks.

It still seems like a nice one to have in the standard, to me.

Cheers,
