If you know a lazy man and the likelihood is that you probably do then this is the mug for them. Lazy men tend to drink beer and lots of it. So either take the beer off them or just get them this mug.
The Lazy Man's Mug is a 3D mug and has a urinal attached to it, so if they really are lazy they can drink beer without interruption.
The mug is very big, more like a stein so they can fit lots of beer in and have somewhere to dispose of it afterwards.
