Godzilla Related Turbulence

Another animated gif from Simpsons episode 30 minutes over Tokyo.

The last part when the pilot says:
“Uh, folks, we’re experiencing some moderate Godzilla-related turbulence at this time, so I’m going to go ahead and ask you to put your seatbelts back on.
When we get to 35 thousand feet, he usually does let go, so from there on out, all we have to worry about is Mothra, and, uh, we do have reports he’s tied up with Gamera and Rodan at the present time. Thank you very much.”
