[Evelle picks up a pack of balloons]
Evelle: Do these blow into funny shapes and all?
Grocer: Well, no, unless round is funny.
listen to it here
Soon thereafter, Evelle is questioned by his brother, Gale Snoats (ably played by John Goodman ) concerning same said balloons:
Evelle: I got me some baby grub, baby wipes, diapers, then disposable kind. I also got a package of balloons.
Gale: They blow up into funny shapes and all?
Evelle: No, just circular.
Hope that explains it sufficiently.
