I Love You Mom
'I Love You Mom' is heard in the 19th episode of the series' first season which originally aired on May 10, 2008. It's definitely one of the more sentimental songs performed by the cast. In this song, the kids are showcasing their appreciation of their mother through music. Candace wrote the song for Linda expecting that she wouldn't be as grateful for it in comparison to what Phineas and Ferb might've planned for her. Phineas and Ferb caught wind of this and had secretly recorded the song without Candace knowing and they all performed it in front of Linda.
