Logic Put the Fear of God into Pinky

So here's Pinky's career progression over the last 30 years :
BBQ Server
Community College Teacher
Unemployed Bum
Zoo Keeper

Here's the horror. After Pinky left the zoo, he was again an unemployed bum. Now he is back to community college teacher. See the pattern? Pinky is fearful of being an aged BBQ server. He sees it coming.
