Tooth Brushing

Charlie Brown just left the dentist feeling happy and excited after receiving clear instructions on proper tooth brushing. Eager to put the dentist's advice into practice, he invited Snoopy and Linus to join him in demonstrating and mastering the techniques together. The entire short is framed as an educational moment where Charlie Brown shares what he learned.

During the demonstration, Snoopy humorously grabs Lucy's toothbrush instead of his own, which shocks Linus who reacts with horror at the transgression. This is played as comic relief rather than having deeper motivation, Snoopy is simply being his whimsical, mischievous self. Lucy never discovers this happened because Snoopy quickly swaps her toothbrush back onto the counter before she notices.

Lucy enters the bathroom with her usual bold personality and immediately interrupts Charlie Brown's lesson to assert her own brushing abilities. She confidently claims to be the best at brushing teeth and continues demonstrating with her own toothbrush, displaying the competitive, assertive character trait she is known for in the Peanuts franchise.

Before they leave, Charlie Brown mentions that the dentist wants Linus to return soon for instruction on dental floss. This serves as setup for Snoopy's final comedic moment, he suddenly produces a packet of floss, snaps off a short piece, twirls it theatrically, and uses it. It ties up the educational theme with a humorous punchline while showing Snoopy paying attention to the full lesson.

The dentist mentioned Linus should come back for floss instructions earlier in the scene.

As Charlie Brown and Snoopy walk away, Charlie Brown delivers this line with his classic sigh of affectionate exasperation. He doesn't actually want a different dog, it's his way of expressing fond bewilderment at Snoopy's bizarre behavior throughout the short, from using Lucy's toothbrush to dramatically producing floss. The line reinforces their close bond despite Snoopy's eccentricities.
