Take a Duck Tour: Go to the Museum of Science (Red Line to Park Street, Green Line to Science Park), and the ticket window is near the back of the Museum. It's about $35 and it's a great tour of the city, as well as a trip down the Charles River. Hell, check out the museum afterwards also. They have one of the largest Van de Graaff generators in the world there.
One of my favorite greasy spoon restaurants is on Beacon Hill. It's called the Fill A Buster and it's located right next to the State House. The Spinach Pie is great.
Just sit on the Boston Common and have some roasted nuts.
Check out the Public Gardens for a ride on the Swan Boats. Red Line to Park Street, Green Line to Arlington. They're closing soon, but it's worth at least trying to get a ride in.
