Jonathon Green, leading lexicographer of slang, toasts the history of the drunken euphemism:
It all starts, as it should with booze, or rather bouse or bowse, which turns up in the very first slang dictionary’, Robert Copland’s Hye Way to the Spitel Hous, published c. 1535. ... After that, the terms come thick and fast. There’s a simple group of similes; [drunk] as a bastard, bat, boiled owl, brewer’s fart, cook, dog, fiddler (or his bitch), fish, fly, fowl, hog, king, little red wagon, lord, monkey, pig, piper, poet, skunk (in a trunk), tick, top, and a wheelbarrow. There is also, of course, pissed, often, if implausibly as a fart, newt or rat.
