It probably has something to do with Lily leaving Marshall a couple of months before their wedding (as there was never any contention between them mentioned or shown prior to this). 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".
