Question: in meet the fockers is jorge greg son

Answer: Yes, Greg and Jack's relationship goes off with a bang when Greg is left alone to babysit Little Jack, whom Jack has been raising via the Ferber method. Despite Jack's instructions to leave Little Jack to self-soothe, Greg is unable to stand listening to Little Jack's cries and tends to the boy to cheer him up by hugging him, letting him watch TV, acting funny, and inadvertently teaching Little Jack the word ``asshole.'' Disaster strikes when Greg answers a brief phone call from Roz, which is long enough for Little Jack to wander out of his playpen (after being opened by Jinx), put on Scarface and glue his hands to a bottle of rum. After a furious argument with the Fockers and his own family (though amends are quickly made), Jack resumes his spying on Greg and sends Greg and Jorge's hair samples for a DNA test, while inviting Jorge to the Fockers' planned engagement party in the hope of getting Greg to admit he is Jorge's father. At the engagement party, Jack, who automatically assumes that Greg knew about Jorge and has deliberately been keeping him a secret from Pam, introduces Greg to Jorge. Later, when Greg denies knowing anything about Jorge, Jack still refuses to believe him and drugs him with truth serum to make him talk. On stage, Greg uncontrollably blurts out that Pam is pregnant and that Jorge is his son in a Darth Vader-esqe matter before immediately losing consciousness.
