Hampden is to Gilligan as the Maryland Science Center is to. . .

Here's a good one:

From the invitation for the Maryland Science Center's annual solstice party (a couple weeks back):

"Think Hamptons not Hampden.
Think Linen not Lycra.
Think Gatsby not Gilligan."

You know: Classy. NICE. Not like Hampden!

Well played, Maryland Science Center. Well played.
