The cork goes back into the bottle of wine and it's abandoned on the ground right before Porthos unbuckles his scabbard (swords get in the way of brawls). Then Porthos lunges for Aramis, aiming to wrap his arms around his midsection and use his momentum (if, sadly, not his weight) to carry him to the ground - or, at least, interrupt the litany of compliments he has no business receiving from his friend. He is, of course, grinning as he does so; it's hardly the first time they settle some teasing with a good brawl.
