Diamonds are a Delta's best friend!
This is silly but other crewmembers are doing it and it's fun.
I don't actually have any like that, but diamonds are a thief's best friend and hey, they'd make Kerril laugh. Anyone on board would see them when we have saunas; no surprises there so to speak--but Londo? Why would he want mine? I thought his underpants would have to fit him like a glove if you see what I mean.
