As for penises in beer, it is known as a "foreskin shandy".
Usually served up to the higher ranking people as the evening approaches the end.
There has been known for the odd glass to be filled a little in the process as well, [by this stage the boss has lost his sense of taste, and the act is well reported at morning tea the next day by the misscreant, if they can remember]
Hahaha. A foreskin shandy, that is funny. High jinks indeed!!
