Think like Jerry....hmmm...I'll try...
If I get rid of this puppet too soon, people will know I made a poor puppet-purchasing promise (a 4P!).
I paid for this puppet, and I'm going to get my money's worth for this puppet. But if I could get rid of the puppet, without people knowing and not have to pay the puppet, the puppet would've been left on the tarmac in Atlanta without a ride home. Then, I'd pick me a new puppet who makes me comfortable.
Burt for now, since its visible, I'll ride out the promise with this puppet.
Plus, I'm not a fan of puppet shopping.
