Ralph asks the counterman for "a couple of cups of coffee," but the man gives him three.
(Ralph)"Let's face it Alice, we have been past the age of rollerskating, since Alf Landon stopped being Presidential timber!"
Ralph to Norton: "I'm going to learn all the latest expressions! Bo-bo-de-oh-do, 23 skidoo, I'll kiss and meet you later, I'm eatin' a patater!"
Voice: "Do the Hucklebuck"
I thought that the girls were very insensitive to Ralph. They could see that Ralph could barley stay on his feet. And they still insisted that he get them coffee. And they just got angry at him when he pleaded with them "But, it's (the coffee concension stand) all the way over there!"
It would've been nice if the girls had gotten up and taken the coffee from Ralph in view of how much trouble he was having keeping his balance on the skates. Trixie even glances at him and goes back to chatting with Alice. They DESERVED to have coffee spilled on them!
A female audience member is clearly heard saying "Don't fall down" when Ralph is trying to learn the Hucklebuck. Later, at the rink, possibly the same spectator is saying "Steady-steady now" as Ralph is trying to bring over the coffee while on roller skates.
