Whats a B-38? 
Jokes are always ruined when they need to be explained.
'B-38' is my way of suggesting that the 80th gang drives a bunch of porky, medium bombers with the roll rate of a fat, drunk woman you brought home from the pub last week.
You see, since Del is a better stick than I am, my only recourse against him is making fun of his chosen mount.
Hence, 'B-38.'
