After your comment this morning I tried to imagine John and Rodney sparring with dirty limerick put-downs...
John looked across the fire at Rodney and smiled.
"There once was a doctor named Rodney
Who thought when he fucked he was godly.
But when he was well-screwed
He became very rude,
And started to act up quite oddly."
Teyla and Ronon laughed. Rodney's eyes narrowed and then he lifted his chin.
"There once was a major named Sheppard--"
"Who thought he was hung like a leopard.
But it was just the spots
From syphilitic twats
He broke off suddenly as if paused by a remote and stared blankly into space.
"Warranted the comparison?" suggested Teyla.
"You've dug a hole for yourself," John said, looking satisfied.
"Shut up!" Rodney glared daggers at them, then recovered and drew himself up again with a look of triumph:
"That made him a cat that was peppered."
John stared, mouth slack. "That's *terrible*."
With an offended expression, Rodney huffed slightly. "It's your fault for having a stupid name."
