No, there are plenty, most of the comedies end on good notes like that. Much Ado About Nothing, As You Like It, Measure for Measure, they are all comedies, though Midsummer Night's Dream is probably the MOST comedic out of all that Shakespeare has written. It is so filled with jokes, punnery, double entendre and silly mishaps that it is pretty muc hthe essence of comedy, whereas most of his other comedies still have some aspects of tragedy in them.
