Steve,
The ship may have looked the business but the champagne bottle wasn't!
Oh dear, it wouldn't break!
And the two bimbos doing the naming were sharing a brain; when asked if they had been on a cruise ship, one of them said "no" while the other said "Yes, we went to France".
Whereupon her sister replied "That was a P & O ferry darling"!
Ho hum!
