What did you do?

go fish

What did you expect to see?

something funny

What did you see instead?

go: unknown subcommand "fish"
Run 'go help' for usage.

I support this.

[cznic]

go home could print you're drunk.

[thediggu]

This needs to happen

[lambdaq]

I suppose the correct grammar should be go fishing

[as]

Bike shedding, but my suggestion for joke text output is below.

go: unknown subcommand "fish"
Run 'go help' for usage.

[0xmohit]

go fish could redirect to the tour.

[KernelDeimos]

My suggestion would be that it displays a random playing card, like "♠ A"

[as]

>go fish
♠ A

My sense of humor is unfortunately too simple-minded to comprehend this particular comedy.

Perhaps the command go fish -v should explain the output to the laymen so that they may too froth in the purposeless but self-satisfying mirth.

[KernelDeimos]

I would expect -v to spell out a card name, like "ace of spades" instead of "♠ A", while -h would provide an explanation

[as]

go fish --desired-card-list={00000000-0000-0000-0000-000000000000},{00000000-0000-0000-0000-000000000001} \
 --desired-card-list-input-type=GUID \
 --output XML \
--color=/dev/moodring \ # save for Go2.0 or when window implements /dev
--broadcast=wss:///golang.org/fish/room/{EFF1000-0040-0000-0000-000044000220} # share the joke with your friends
 -mmmmmmm # each 'm' increases mirth level

Okay, I created patch.

We don't want to put jokes into the go command, sorry.
