The end of the Mother's Day episode with the poem Chuckie's mom wrote for him.
My Sweet Little Chuckie
Though I must leave you behind me,
this poem will tell you where you always can find me.
When a gentle wind blows, that's my hand on your face.
And when the tree gives you shade, that's my sheltering embrace.
When the sun gives you freckles, that's me tickling my boy.
When the rain wets your hair, those are my tears of joy.
When the long grass enfolds you, that's me holding you tight.
When the whippoorwill sings, that's me whispering, "Night night."
- Arguably the entire episode, although special mention goes to the scenes of Tommy and Phil and Lil talking about their mums. Specifically, Tommy refers to him being in a "giant fishtank" (an incubator) and Didi comes in and holds his hand, while Phil and Lil mention that they first started laughing after they were fed "the old way" (breastfed).
