Though Marshall and Lily eventually made up, it would appear Judy never forgot. She also didn't like that Lily refused to be a "Mrs. Eriksen" by keeping her own last name.

- Bald of Evil: Not evil... most of the time. But when you consider he taunted Marshall while he got lost in a house during a blackout...

- When Marvin was finally born, Marshall finally gets over his own dad's death.

- Woman Scorned: When she was still The Ghost, Robin is seen talking with her on the phone. Robin leaves the phone while she goes doing something else, because she is talking non-stop about how much of a jerk is Robin' dad.

The day of the wedding, Robin's mom was indirectly comparing her own past marriage to Robin's dad, "hoping Barney is nothing like him".

- Long-Lost Relative: Only meets her half brother when he was reunited with their father.
- Red Herring: A lot of viewers assumed that she might be the Mother....until Season 8's episode 14, "Ring Up".
- Shotgun Wedding: Almost pushed into this with Ted by Barney after the latter found out that she hooked up with the former.
