"Sign me up" in informal english

[Shinobee]

I heard this idiom under the situation below.

One was talking about the medicine he takes, and another responded that "Sign me up". I guess he needed the medicine or he reckoned that the medicine could cure him as well.

I think its the humorous way to say "I need it too!" in a poetical manner.

I'm not sure though. Can y'all give me a help..?

I don't know about the poetry of it, but you have the right idea.

You can't say "y'all" unless you're sitting in a saddle. And we would ask for "a little help," rather than just "a help," pardner.
