A little spooky to be honest.
Looks creeeepy but for some reason I don't think its that hard to do it. Of course I have to try it. Lol
LOL I can laugh without smiling and I'm pretty sure I'm creepy when I'm doing it!
I too couldn't do it, I'd keep cracking up!
When I try it I sound like Mr. Ed saying Wilburrrrrr……
Stewie Griffin does it best
