You can make a nice pint glass by placing a negative cone inside a positive cone, then using a positive cylinder for the bottom and a negative cylinder to "lop off" the pointy part of the cone. Group them all and turn upside down. Now you have a tapered pint glass. Repeat this without the negative cone or positive cylinder, group separately, place inside the glass and scale to fit. Texture this the color of your beverage and voila! Pint of Guinness (which I had a few of last night, yum).
