"Come out with your hands up… and something with coconut" [closed]

The expression Come out with your hands up is a very serious command from a law enforcement officer:

The irony of combining that serious command with the silly shopping list might strike a funny bone:

It's a slight pun or play on words, because there are two meanings of 'with':

• Come out "with your hands up" means 'being with your hands being up'
• Come out "with two cups of coffee" means 'possessing two cups of coffee'

The contrast in tone should make it amusing or silly:

• With your hands up is very serious (you may be shot by police)
• With coffee is very every-day and friendly

"... and something with coconut on it" means '... and with candy or a donut or something', which is a joke about Chief Wiggum's perpetually wanting donuts:

Judging by the first part, the sentence is an order issued by a police officer to a suspect or suspects.

It is humorous because the police officers are mixing a legitimate law enforcement command, "come out with your hands up", with inappropriate requests for general goods. In effect, they are have the suspect shop for them while making an arrest.

Furthermore, the list of goods requested contains an absurdly specific item, the air freshener with a specific astrological sign, and an extremely vague item, the "something with coconut on it".

These juxtapositions are intended to be funny, and to a degree they succeed.

I think the second part of the command, more than a shopping list, is a reference to a game called scavenger hunt. This makes it even funnier by virtue of contrast with the first part.
