Ernie tries to borrow a vacuum.
I actually don't know very much about this Herbert Birdsfoot character, but he seems to be kind of a lecturer and generic straight man, often paired with Grover, apparently.
I don't know about you, but when Ernie says he needs to vacuum, I imagine Bert fainting from shock just off camera.
To a certain extent, this is the story of my life. I've been meaning to call my sister for months now, but I haven't because I'm never sure when would be a good time. And school's starting soon, if it hasn't already, and then their schedule gets REALLY crazy.
