Basically whenever Zeus opens his mouth. Or writes something. Or just plain exists.
Zeus was the one designing and writing the painfully gaudy quiz.
Why is the game needed in the first place? Because Zeus got fed up with everyone and their mother bitching about how Zeus ruins things and they would be much better rulers, he decided to create a competition with his throne up for grabs.
The video instructions for the test and the game. It... has to be seen to be believed.
Zeus' status on the communicator device the gods use is "God of ur heart ;)"- yes, with a wink. They were not even subtle.
To give Bobby the package, Zeus took over the place of the principal for a while, even crossing out the nameplate on the desk with a sharpie. Zeus claims no harm has come to the real principal.
Bobby claims there must have been a mistake, Zeus' answer is that she does not make mistakes... and when she does, they're "not this insignificant" (as in, not as small as giving the parcel to the wrong person.)
Zeus and her mortal, Ellie (yes, her- the game provided the King of the Gods with a female form) meet Hades and Max. Zeus remarks Max looks cute... to which Ellie says "Eeew, he's, like, literally an EON younger than you", and Hades quips "Let's not forget Zeus' marital status." Zeus promptly demands a change of topic.
"Is 'dick' another word for 'deity'?" "Based on what I saw... it might as well be..."
"This is Eris...Dickess of Discord!" *Cue Face Fault*
Talking of said meeting... After finding out what's expected of her, Bobby breaks down slightly, wanting to be alone. She yells at Poseidon to leave, but Poseidon makes her cry by yelling back for her impunity. Poseidon's attempt to stop Bobby's tears is priceless, so is Bobbys fainting, to say nothing of Poseidon trying to revive her.
Poseidon also blinks in confusion when addressed as madam, and takes a look at the mirror... then gets a minor freakout looking at a beardless, female body. Even better when you remember that Poseidon is often jokingly referred to in some works about or dealing with mythology as Barnacle Beard, see Percy Jackson as an example.
