This must be a stock comic. The punchline could have been anything. Anything at all. Instead of something clever, we get "It's Payday." What? Is Heathcliff whiffing at a delicious candy bar? I thought he preferred Baby Ruth, but he must be craving the pure peanut goodness hidden beneath that plain, unassuming wrapper. It must be that - what use does a fucking cat have for fucking money, and why would any cat follow the recipient of the money to the bus stop?
Also, nice 1930's lunch box, cockbag. I hope you have an enjoyable day on the girders of the unfinished Empire State Building.
