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

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