[Esel Mann]

So some ideas (taking into account the weather and in no particular order of sillyness):

MFA - Always something kool going on there. Security and staff are kinda creepy though.
Mapparium - Ask for Tom Cruise.
Mass Ave bridge - See exactly how many Smoots long the bridge is.
Top O' the Prudential: Great way to oversee it all (weather of course dependent)
Harpoon Brewery Tour: Be sure to ask for a Sam Ale during the beer tasting.
Sam Adams Brewery Tour: Be sure to ask for a Harpoon IPA during the beer tasting.
Fed Reserve: At the end of the tour, get a postcard from the gift shop. Title it "From the Fed with Love, We're Watching You!!!". Send to TABS USA.
O'sullivans: Great lunch. Be sure to talk Yankees baseball.

And.... You know... You seem like a squire, know what I mean? Wink, wink, nudge nudge:
Golden Banana on US1 in Saugus (if you can Uber)
Glass Slipper (Chinatown cough cough Theatre district alternate).

And if that's not enough, you could tour the former homestead of Pelican A-list Celebrity Esel Mann. Now I'm not sure the current owners know. But hey, after they leave for work, if the door is unlocked, what the hell, have a look see!
