For emphasis try an exclamation point after Uke. As in Fuck Uke! (A comma between fuck, and Uke would render the effort meaningless, or questionable at best. just sayin'...)
Remember commas separate objects in a sentence, or begin a list, or indicate a change in subject.
This ends today's grammar lesson. Stay tuned for more.
