It鈥檚 tough to be a television LEGO genius when Will Arnett is cracking you up on set, but that was the challenge for a brother-sister team from the Lower Mainland.

The Canadian actor who is known for his roles on Arrested Development and BoJack Horseman is the producer and host of LEGO Masters, a TV show that brings people with a passion for the iconic plastics bricks into a competition for a $100,000 prize.

David Guedes, 36, is a LEGO lifer who successfully auditioned for the show, and for his partner chose his sister Emily Guedes, 34. The show was finished shooting some six months ago, but they鈥檙e just watching it now. Last Wednesday they saw the airing of their Week Three challenge 鈥� to create a LEGO bull riding character to mount an actual mechanical bull.

They came up with Toby the Birthday Pig, who it turned out was not in the saddle for long.

鈥淣obody has ever done that before 鈥� that鈥檚 a crazy challenge,鈥� said Emily. 鈥淭ypically you don鈥檛 build LEGO to see it smashed.鈥�

The next episode, which airs on Oct. 12 on CTV, will see the contestants building a tree house, with their younger selves in mind, which must be built in real trees.

They鈥檙e not talking about how the series turns out, except to say that they had a great time.

鈥淭he people we met on the show are like family now,鈥� said Emily.

They were fans of Arrested Development, and of Canadian actor Will Arnett who played George Oscar Bluth.

鈥淗e鈥檚 exactly like that (character),鈥� said Emily. 鈥淲e were laughing constantly.鈥�

David, now a Surrey resident, recalls their childhood in Maple Ridge with lots of LEGO in the scenes, starting with a big bucket of hand-me-down bricks when Emily was still just a baby.

Now she works as a nurse, and he is a Learning Centre Supervisor at Douglas College, but Lego has always been part of their lives. In 2016, David joined a BrickCon organization, for AFOLs (adult fans of LEGO).

鈥淚t鈥檚 amazing their genius ideas, and the things they can create,鈥� he said.

Now he owns about two million bricks, and still loves to get yet another new LEGO box.

鈥淚t鈥檚 like a LEGO store in his house,鈥� explained his sister.

Emily also still enjoys putting together LEGO sets, which she finds as therapeutic as other people do knitting or colouring.

鈥淭he puzzle aspect of it was always really fun to me,鈥� she said.

The LEGO-loving siblings found that during the challenge they could disagree, or one shoot down the other鈥檚 ideas, without any bruised egos, bickering, or silent treatments.

鈥淪he鈥檚 a great teammate 鈥� we get along better than anyone else,鈥� said David.

Now they are enjoying reliving the competition, as they watch it on television.

鈥淚t鈥檚 almost like watching a memory bank,鈥� said Emily. 鈥淲e were laughing all the time 鈥� it was so much fun doing it.鈥�

David would encourage anyone thinking of an audition to get involved, and see how they stack up. He said most LEGO masters have some capacity for thinking like an engineer.

鈥淏ut also being a little wacky is good.鈥�
