One is the quiet type who loves fishing and playing second fiddle on the footy field, while the other is the confident socialite who takes control of his team.
Tyrone Roberts and Jarrod Mullen may be different in so many ways, but their combination on the field continues to prosper.
Now in their third season together in the halves for the Knights, Roberts and Mullen have been rewarded with selection in the Country Origin team to take on rivals City in Dubbo on Sunday.
It's a special feat for both players, but particularly Roberts given it's his first taste of representative football.
"Mullo and I play at club level, but this is my first rep side so what better way to do it than with my halves partner at the Knights," Roberts enthuses.
"It means a lot and I’m going to have a lot of family out there in Dubbo supporting me.
"So hopefully I can put on a good show for not only my family, but also the country lads."
It's a feeling backed up by Mullen, who couldn't be happier to play his fourth match for Country alongside his little buddy in the No.7 jumper.
"Like I said the other day, I was probably more excited for T (Roberts) than myself," Mullen says.
"It just shows how hard he has worked. He is getting an opportunity now and hopefully we can both take it with both hands.
"The whole team was pumped about having the five boys in the one team, now that Robbie Rochow has come in.
"It looks like there is a good bunch of blokes in the side, so it should be a good week."
Roberts and Mullen may click on the field, but they are first to admit they are different personalities away from the bright lights of the NRL.
Asked if they hang out when they are not at footy and training, Mullen jokes, "He doesn’t leave the house.
"Him and his missus just sit there and have cups of tea and you never see him out and about."
It's a cheeky sledge that's swiftly shut down by Roberts.
"No mate, I go fishing," he says smiling.
"Snapper, a bit of dewey, I sit out on the lake and get out of the house."
While it's a reply that's lost on Mullen, who concedes he is the furthest thing from a fisherman, he believes it's these personal differences that make the pair combine so well together.
"I suppose everyone is a bit different and special in their own ways," Mullen says.
"But it definitely helps, because Tyrone and I have been playing together for five years now.
"And I used to watch him when he was coming up through Wests when I played there as a junior.
"It’s also a good thing for Wests Newcastle to have two local juniors in the halves coming through and playing for country.
"So it should be exciting for them as well.
"Hopefully we can go out there and make the country people proud, because I’ve still got a lot of family living out there in the country so it will be good for them to watch us."
Roberts is equally excited about playing for Country with his teammate by his side.
"He is normally the dominant one on the field, so I’m just going to chill, take a backwards step and play my own game," he adds.
"Hopefully on the weekend, we can get that combination going again and play some good football."
You can bet that's exactly what Newcastle's odd couple will do come match-day on Sunday.
