No, kid - what the HERK is that.

I assume HERK refers to Hercules, since there's also a Caesar reference and some columns. So it was the Roman Hercules.

The other stunt men are unnerving - Movin' Marvin, who looks like some late-stage WW1 invention that led to the death of everyone who rode it, and Knight Rider, whose trademark was probably bought out by the TV show people.
