Mae 'Maeby" Bluth Fünke is the daughter of Lindsay and Tobias.  Though throughout the series they made references that Maeby was actually a test-tube baby.  Who really knows with a never-nude for a father.

Maeby has never really been one for school, is often a troublemaker, and eventuallly lands a job at a studio, despite the fact she was only 15.  Marry me.

Maeby shows mutual attraction towards her cousin, George Michael, but doesn't act on it for obvious reasons.  Meanwhile, she dates Steve Holt, who also turns out to be her cousin when Gob is revealed to be Holt's father.  Some girls have all the luck.

When she finds out her mother was adopted, it turns out she wasn't related to either of the cousins she made out one.  Maeby: 1, Universe: 0.
