Don't you know we follow the Brits up here, rather than simply copying whatever you Yanks say is right?

Leave it to the English to bugger up a perfectly good language, amirite?

For the record, the use of 'fork' to refer to the individual prongs of a fork (thus, in cases, pluralizing the implement) dates back at least to to the 17C.

For 20C usage, take this bicycle-specific example from the 1957 Encyclopaedia Britannica III. 544/2 (courtesy of the OED): "The fork crown (at the top of the forks) is fixed to the steering column."

I suppose all those who find this linguistically unbearable object similarly to the apparent pluralization of 'pants'...
