7 votes so far, and it seems that I am the first to post.
Before this I have not heard of the day.
According to a search I did just now, the day is September 19.

By the way, I voted "What".

2 votes tell they did.
4 for "What"
1 vote tells forgot.

...another 'Aye' from me.

Huh...it is very nearly tied at the moment. Considering I had only heard of it from a poster I happened to see, I can see why. & apparently no one at my university celebrated it in any detectable fashion.

I did, it's my friend's birthday...aargh!

Arrrrr!!!!!
(This is fun)

voted Aye

Arggg.
does anyone know how to make an ascii pirate?

No, but I can use google. Give it a try, the results are amazing!

Found one. Looks like this

_____
.-" .-. "-.
_/ '=(0.0)=' \_
/` .='|m|'=. `\
\________________ /
.--.__///`'-,__~\\\\~`
/ /6|__\// a (__)-\\\\
\ \/--`(( ._\ ,)))
/ \\ ))\ -==- (O)(
/ )\((((\ . /)))))
/ _.' / __(`~~~~`)__
//"\\,-'-"` `~~~~\\~~`"-.
// /`" ` `\
// jgs

Whoops. That did not go well

Try the URL to find a lot of ASCII art.
