Barney an Dora give Sally tips and show her how they neck in their auto... a mime ensues.
They then mime boating on the river but are interrupted by the Dean who takes Dora away to tidy away a pile of large books.
The fat girl returns picks up the entire pile of straws and drinks all the punch.
Dora goes to refill the punch-bowl, giving Barney a huge lump of ice to hold.
