John McGuire

John McGuire was a houseguest on Big Brother 17.

John is best known for his very loud and very funny diary room confessionals. Despite being one of the most nominated houseguests in Big Brother history, he managed to get off the block four times by winning 3 PoVs and 1 BOTB. His closest allies were Becky Burgess and Steve Moses, and his primary target was Vanessa Rousso since he was the only person in the house to realize how much of a threat she was. In week 9, John and Steve were both nominated for eviction, and ultimately he was evicted unanimously. However, he managed to re-enter the game by winning the jury buyback competition. Upon returning he started working with his arch-nemesis Vanessa, and made Austwins his new targets. Despite managing to lay low and improve his social game with the remaining houseguests, Vanessa evicted him on day 91 because she was scared that he had a final two deal with Steve. He placed 4th and became the 8th member of the jury.

On finale night, Johnny along with Jason and James was revealed to be the top three to win America's Favorite House guest, but lost to James.

He is secretly a super fan of the show, but kept that status a secret to avoid being targeted. John also tied with male Pov record with 4 wins each shared by James Rhine and Shane Meaney. He became the first male to save himself three times with the Power of Veto.

Biography
John (aka Johnny Mac, the Rock Star Dentist) is unlike any other dentist. He is loud, goofy, and never seems to run out of energy. Recently, he’s taken up running Tough Mudder marathons and is excited at the prospect of having a few showmances. Single and proud of it, if any girl wants more of a relationship, he has a sure-fire way of getting out of it—he'll start acting completely annoying and geeky, so they end up dumping him and no hearts are broken. He's a closet super-fan and wants to win so he can save his parents’ lake house and finally pay off his school loans.

John is from Scranton, PA and attended undergrad at Penn State and medical school at Temple. He plays guitar and bass guitar, though he wants to learn how to play the electric violin next. His favorite musicians include Dave Matthews Band and Skrillex, though he said he listens to all music except country.
