Well, now that's pretty vague. What immediately jumps to mind is that "this post is brought to you by the letter K."
Kim.
Kooky.
Kind.
Kraft-y (as in cheesy).
Karma.
Kids.
Keen (in more than one way).
Kick (used to do that in Tae Kwon Do).
Kayak (a palindrome).
Kodak (I like taking pictures).
And, finally, my picture of the day. Of course, it's the letter K, more commonly known as potassium. It's also the 19th element on the periodic table. And it does not react well with water. Danger, Will Robinson, danger.
