This is the n-th cartoon of this bland style.

• The redundant shirt and speech bubble
• the lack of a proper punchline
• weird smile on the right dude
• fingers

This same style is popping up everywhere.

Look for style consistency, including lettering, colors, line thicknesses, character features (e.g. number of fingers, shapes of facial features)

If it looks like a sepia pip-boy cartoon, it’s most likely AI. For some reason that’s the default cartoon style it generates.
