I don't know if you can tell, but I grew up watching a lot of television.
Guy on the plane I'm on has a text alert that sounds like a gunshot... And he isn't putting it on vibrate.
Everything is awesome... Everything is cool when you're a part of a team.
I love President Bush. I think it's great we have a president who always looks like he's looking directly into the sun.
I love John Madden, because he makes me feel smart.
It's a simple and an effective way of getting everyone on the same page, prepared and paying attention to the gag. People just get into that frame of mind of you doing impressions. It can take a minute or two for an audience to catch on when you aren't doing one.
