Ships in Bottles

"Booby Trap". While preparing to explore a derelict Promellian battlecruiser, Captain Picard waxes poetic about building ships in bottles in his childhood... to blank looks from Riker, Worf, and Data. Worf gruffly informs the Captain that "I never played with toys" (befitting his stodgy personality), while Data, being an android, reminds Picard that "I was never a boy." Chief O'Brien knows what he's talking about, though.
