[spoiler]Wednesday's quote:
Ep #73 (1966) - David - 'Gee, you MUST be a genius.'
From "#0073/0074: Robservations 07/12/01: Two Collins in the Monster's Lair"
Has anyone ever told you that you have a great smile? asks Sam. David shakes his head and says no. You have, and I'd love to paint it someday, says Sam. Are you an artist? asks David eagerly. Am I an artist? asks Sam--son, I can take a raging storm and turn it into something beautiful!--I can take a buttercup and breathe eternal life into it! You must be a genius! says David. Not quite, says Sam
The Robservations references the quote almost perfectly...
