Another Easter Egg that has been removed in v6.10.
Ouch!, Eek!, Yikes!:This is a well documented easter egg on many sites, but I'm posting it just the same as a tribute to it and Khaled's cult sense of humor.  When right-clicking on the right-most toolbar icon, a tooltip box would appear containing one of the following phrases with each click.
ouch!,  eek!,  yikes!,  moo!,  erk!,  :P~~~,  It's life Jim...,  but not as we know it,  Ni!,  *positive karma*,  oink,  With a rubber duck...,  one's never alone,  -gribbit-,  hi MOM!,  hoohaa!,  I'm a Tigger,  are you?,  nanoo nanoo,  BaDOOM!,  Mork calling Ork,  Yak!,  Whatever you do...,  DON'T PANIC!,  Grrr...,  Greetings $me $+ !,  :
[/b]),  That's all folks!,  Enjoy the ride :[b]),  woowoo!
If you recognize at least 5 of the above references, you're a typical geek in their mid-late 20's.
Scary, ain't it.  

However, now when you right-click this same icon, it turns into a smiley face.  This use to happen when you held Shift and clicked on the icon in v6.03 and earlier.
