A friend of mine, who is a rather large fellow (6' 6", built like a brick shithouse. Rugby player), amuses himself by ordering half-pints of things in the College bar - all the half-pint glasses the College bar has are the miniatures of the large ones that are straight edged from the bottom with a bulge up top (I think the design is called the "nonic" pint glass).

The reason? His hand completely envelopes the half-pint glass, so he jokes that he imagines he's drinking from a pint glass: makes him feel like a giant.

It's actually really fun to do!
