This is pretty self-explainatory, if you studied chemistry in high-school. It is a phun on the trademarked brand Snapple, which is a collection of juice and fruit drinks. Cueball gets an offer to try out a Snapple in the form of an apple and tries to bites it, but is not able to. Then, he learns that the Snapple is actually an apple infused with Tin. The periodical table notation for Tin (so says the image text also) is Sn. Combined with apple, you get Snapple.
Anyone knows who James is?

Don’t know who James is (he inspired a couple of early XKCDs). I note that the word “Snapple” originates from ta “snappy” carbonated apple beverage that Snapple originally produced, rather than from any connection to Tin.
I enjoy that Randall put a frame of silence in for comic effect. It as if either he’s waiting and no one laughed… or he’s waited the appropriate amount of time it takes to get the joke. Either way, it adds to the effect.

“Anyone knows who James is?”
No, but I suppose it is someone Randall knows. And I suppose it is not important for the comic.

Also (just to torture the pun a bit further), although I doubt it was in the original intent, you could read it as Sn=Sin, i.e., The Apple that Adam & Eve ate, infused with original sin.
But if it had been a tin apple, they never could have eaten it, and we’d all still be in the garden of Eden…
