Penguin cartoons. A penguin playing a guitar.
A cartoon showing a penguin playing the guitar in a band. Another penguin is playing the drums.
The guitar playing penguin is thinking “Playing chords is really hard when you’ve only got flippers”.
This cartoon is partly funny because penguins look like humans but don’t look like the sort of humans who would be in a band playing guitar and drums.
This cartoon would make a very nice greetings card.
