National Lemonade Day
Aug. 20-23
Prohibition Bakery, 9 Clinton St.
$2-$20

Novelty “holidays” may be silly, but that’s fine by us when they come with specials like the Blueberi Lemonade cupcakes at Prohibition Bakery, helmed by two bakers as passionate about dessert as cocktails. The cupcakes, featuring Stoli Bluberi, run $2 apiece or $20 for a dozen Aug. 20-23. But the best deal is on Day 1, National Lemonade Day, when buying a cupcake also gets you a drink ticket for the Stoli Lemonade cocktail at Bourbon & Watt (5 Ave. A).

In “Love & Warr,” the television star sings pop hits and Broadway tunes with the aim of getting to the heart of, well, the heart. (Note: There’s a $25 food and drink minimum.)

Charlie Parker Jazz Festival
Aug. 21-23
Marcus Gavey Park & Thompkins Square Park
Free

That’s right, Charlie Parker is such a big deal (in jazz and beyond) that it takes three days to do him justice.

Stand-Up Comedy Boat Ride

It’s a dream come true for stand-up comedians: a venue where the audience can’t just walk out if you’re bombing. And it’s perfect for the audience, too, because there’s plenty of cocktails onboard. And if nothing else, you get a three-hour boat ride down the East River for $30, which is an absolute bargain. The lineup is TBD, but will include acts from Comedy Central, HBO and BET.

Misty Copeland: ‘On the Town’
Aug. 25-Sept. 6
Lyric Theatre, 216 W. 42nd St.
$62.50-$157.50 

Broadway’s dance-heavy musical revival about sailors making the most of shore leave in NYC is closing its doors after Sept. 6. But audiences catching the show before then are in for a treat, as American Ballet Theatre’s Misty Copeland — recently named the world’s first African-American principal ballerina — takes on the role of Ivy Smith for the final 12 performances, starting Aug. 25. It’s Copeland’s Broadway debut, fittingly in the show that boasted one of the first-ever racially integrated casts in 1944.

She performs next week at The Jazz Standard alongside the Aaron Diehl Trio.
