I am alternating typing the letters L and O to show that I'm amused

[Bucky]

Then, as I roll around on the carpet laughing, I reach up with one hand toward the keyboard and type R, then O, then F, then I roll around just out of reach of the computer. Seconds later I roll back toward the desk, still cackling uncontrollably, and type L and reach over to the mouse and click the "Post Message" button on the screen.

This incident was not as bad as the time I laughed so hard that my ass fell off. After I finished typing LMAO I had to be rushed to the hospital for an emergency reattachment.

1. alternating the letters h and e

but the are more onomatopoetic and denote a snicker more than uncontollable laughter

heheh

2. May I suggest...

...that you avoid typing WTF, for fear of losing all ability to perform the sexual act!
