What´s your favourite letter?

[Dr. Eddies Wingman]

Obviously T since my first and last names start with it. And I dislike coffee too.

Tanita Tikaram is a Maiden fan?

My favourite letter is w because I like whisky.

It was a close battle between X and K for me, and I ultimately went with X. I just like it a little better, at least today; ask me next week, it might be the other way around.

The letter of the law of course

Ѫ.
Now sadly gone, and replaced by that Ъ impostor, it used to represent a sound ("uh", more or less) that, pronounced the right way, and with confidence, could get you through an entire evening of conversation in Bulgarian without anyone even realizing you're not a native speaker, or even that you might know nothing of the language at all.
Some examples:
Ѫѫ: yes. Ѫ-ѫ: no. Ѫѫѫ: not sure really. Ѫ (rising): pleasant surprise. Ѫ (falling): unpleasant surprise. Ѫѫѫѫ: wossname, tip of my tongue. Ѫ-ѫ-ѫ: 18+

^ On second thought, it might well get you through an evening of conversation in English as well.

XD This is the best post in this thread by far, though the Letter of Marque is a close second.
