Hercules is 'The Responsible One'

Hercules is often "The Responsible One" when Jason and/or Iolaus are goofing off. He tries to stay responsible, but often the taunting of his friends is enough to tempt him to goof off as well - often with consequences.

1.03 What a Crockery

Hercules is on a mission to deliver Zeus's Chalice to Zeus's temple, but Iolaus and Jason talk him into a game of Melonball that distracts them long enough for Strife to steal the chalice.

Iolaus: Guys, you know what I'm thinking?

Iolaus and Jason: MELONBALL! Yeah!
Hercules: No, no, no no! We've got to get the chalice to the temple, all right?
Iolaus: What, you can't handle us?
Jason: I thought you were Mighty Hercules, Conqueror of the Gods!

Hercules: Okay, all right. I guess if we get the chalice to Zeus's temple this week, I'll have time to teach you two a lesson.
