I suggest a reverse of the usual "earth in-joke that confuses the natives!" Instead, Teyla (and maybe Ronon too) is laughing her ass off at the rest of her team for something, and Rodney is getting offended, while Sheppard's stuck explaining to the merchant that, 'Uh... actually we don't want... pie--it's the pie right? Come on--Teyla?"

Because maybe the pie is, I dunno, shaped like the distinctive shit of some animal she grew up hunting.
And you can 1) just have Teyla laughing her ass off as they hold something, and not bother explaining, just give speech bubbles or a caption to hint that McKay and Sheppard are clueless. Or 2) you can have a smaller panel off to the side that's a flashback of younger, or at least in Athosian garb, Teyla looking at the thing that explains it.

Or--! They have to wear facepaint for something, maybe they're being clowns to entertain some kids becxause John's a sucker for kids, and so you've got John painting a stripe down Rodney's cheek--Rodney with his mouth wide open mid-protest--and this intense concentration on John's face, while Teyla is laughing her ass off, possibly while Ronon is holding up a painted finger like he's trying to paint her face. And she's got a bright green nose already.

Or switch it up, so Ronon's trying to paint rodney and looking pretty evilly gleeful.
