Yeah, i found him really irritating in the early episodes but then he started to figure out people were getting fed up of him and he calmed himself down a bit but now there's les people and he can smell the final he just can't help himself and his irritation level has climbed right up there!
I think the defining moment in the game for him (when the others got worried by him) was when he carried Solly like a backpack in that one challenge.
I reckon he's probably even more irritating in the real World. He's a wedding planner isn't he so i can just imagine him pointing everywhere and ordering his minions around.
