TIME OUT. ADAM LEVINE?!? IS ON A TV SHOW?!?! (other than that horrendous <sorry to the fans> show where people sing and his chair spines?) I'm buying this. tonight.
Do your research first. He's on season 2 which hasn't even ended yet and he has a very minor appearance with Tatum's wife.
Yes, but would I really watch season one without having watched season two? And I'll buy based on that gif alone. If that is his only 2 second appearance on the entire series, he has sold me.
Actually, you can. Because the two seasons are completely different story lines/characters/etc. A majority of the cast is the same, but in different roles. It's not your typical show. Each season is a different story.
ETA: Not to say season 1 isn't awesome, it is. But if you're only going to watch if for the 10 minutes of Adam Levine throughout a couple of episodes, you can probably get that on youtube.
