info about an icon/eppisode

Ok so I'm not looking for a fic this time, it's just I keep seeing this adorable icon with Rodney and John giving a thumbs up and pointing thing to each other and there's text saying 'the secret language of gay.' My question is what eppisode is the action from I remember it happening because I thought awww how cute but I can't remember when...

Thanks.
