Characters
Every time I learn something new, a little of the old gets pushed outta my brain, remember that time I took that wine making course and forgot how to drive?
— Homer · The Simpsons

Our reading
An editorial interpretation.
Homer jokes that his mind has limited room, so each new fact evicts something older. His example is deliberately absurd: a wine-making course supposedly wiped out his ability to drive. The line plays self-deprecating foolishness for comedy, treating memory like a crowded shelf.
