Kids realize their parents are full of crap at an early age, and one of the ways they discover adults have been lying to them is by catching us doing something we told them absolutely, positively not to do.
This double standard drives kids crazy, because they want to look up to their parents and respect their authority but can't bring themselves to obey a lying, conformist worrywart with poor math skills.
Jacob Andrews and Willie Muse have cited five examples of What Adults Say Vs What Adults Do in this strip, but I'm sure you can think of at least a dozen more things that make adults totally full of baloney man! Adulthood is a lie!
