1) they took a short course on ice cream making at Penn State
2) they give out free cones to everyone one day a year and
3) I lived above a Ben and Jerry's in college and at $2.99, a pint of ice cream was a cheap and delicious meal.
I am also aware that the company is known for being vocal politically and today they did something I think is awesome. In honor of gay marriage becoming legal in Vermont, they sold pints of "Hubby Hubby." Unfortunately if you don't live in Vermont you probably won't be able to get a hold of it, but you can use a permanent marker to re-label your own Chubby Hubby (the ice cream, not your loved one).
