Ah, another good one to add to the list above would be "algebra".

I do have a fondness for the (not terribly prevalent, but permitted) alternative spelling of "queuing" that keeps the "e", resulting in "queueing"; a whopping 5 consecutive vowels.

I seem to recall reading a newspaper article about an RSI-like injury that had been christened "wiiitis".

[INJ] That reminds me that "buffet" is pronounced "boo-fay" except when referring to catering provision on British trains, where it's "buff-it".

[rab] Really? I beg to differ. "Buff-it" would only be used by me as a verb relating to what strong winds can do to a person.

[Rab] Not to mention the notices on the cross-channel ferries which say: 'To the buffet/Au Snack-bar'

Saying "boof-ay" here would get you strange looks.
