Foolish Mortals by Tom Horacek for August 30, 2021

uhmm…. don’t get the joke

Nice art work.

I was hoping someone here would explain the joke. I see that I am not the only one to leave disappointed. I’ll come back in 18 hours.

I think he walked underwater from the city and has only just started to emerge as the floor slopes up to the shore. Perhaps the comic is simply all wet.

Is grandpa aquaman?

Patient family to wait for him by the shore for 18 hours…

See if this helps: “High tides occur 12 hours and 25 minutes apart. It takes six hours and 12.5 minutes for the water at the shore to go from high to low, or from low to high.“
