Panel 1: Ooooooh! Evil!Becky! April, don't say "um", for gossakes! And I'm still wondering how you were able to "take a later bus". And your hair looks like the 1940s, as if it's in a snood.
Panel 2: "Beeswax"? Jeez, you really are from the forties! Anyway, why are you so defensive? Oh right: it's Becky doing the asking, and she's evil.
Panel 3: BWAH! This is why I only read one panel at a time! But heck, "anymore"? I don't believe people have said "none of your beeswax" in these kids' lifetime!
Panel 4: Crimeny. April looks like she just dropped a load in her drawers.
Panel 5: Such a sad little face. Perhaps she's sad because she was out-punned. As it is, that is no punchline at all.
