Years ago, two of my friends complained about this exactly same scene on two separate occasions:
They said: Chalmers shows up, with an empty wine bottle with a red ribbon on it.
I’m like:
“It’s a wine bottle! Chalmers totally puts it in a bucket of ice”
But they’re like:
“But, if it’s a wine bottle, where’s the cork?!”
And I’m like:
“...But Skinner is clearly seen drinking bubbly out of it afterwards.”
But they’re like:
“But how can he be drinking from it, if it’s empty?!”
…This drove me crazy! Is this like, an animation goof or something? This has bugged me for years!
