My name consists of two letters, so it's not hard to forget.
Allo! You've probably found the right TK.
In case you think you're wrong, ask yourself:
1) Do you know a TK?
2) Have you heard a ban pun in the last day by the same TK?
3) Can you ask TK that this is the right TK?
4) Does the TK you know act sarcastic or funny?
5) Is TK TK?
If you said yes to all of these, then you probably have the right one.
I generally don't like to brag (because I have nothing to brag about).
