LOLCode
I suppose while I'm sending out the random link propagation, I should also mention LOLCODE - the programming language for really leet coders. I think it's related to the (deservedly) esoteric language valgol, from the 80's.
Update: on second thought, some examples might be useful. :)

CAN HAS STDIO?
VISIBLE "HAI WORLD!"
KTHXBYE
A small example of valgol:
LIKE, Y*KNOW (I MEAN) STARTIF PIZZA =LIKE BITCHEN AND GUY =LIKE TUBULAR AND VALLEY GIRL =LIKE GRODY**MAX(FERSURE)**2 THEN FOR I =LIKE 1 TO OH*MAYBE 100 DO*WAH - (DITTY**2); BARF(I)=TOTALLY GROSS(OUT) SURE LIKE, BAG THIS PROGRAM; REALLY; LIKE TOTALLY(Y*KNOW); IM*SURE GOTO THE MALL
