Summertime.

A season for hitting the beach, backyard grilling, and of course enjoying fresh fruit and vegetables. Ever wonder if there was an easier way to eat corn on the cob? Bruce Willis visited David Letterman on Tuesday night to introduce his new invention called Hands-Free-Corn-Eating System.

Willis is an avid musician and harmonica player. His musical influence clearly impacted the design of his hands-free device. The ear of corn is attached to a harmonica neck wrap, which if adjusted properly, will position the sweet treat at mouth level. Willis even showed the audience how to apply butter to the corn with the help of a two-pronged butter hat.

Letterman was game to go along with the bit and shared several bites of the same ear with Willis.

Here’s a look at the clip.

It’s a bit messy, but if you need your hands free in order to hold other BBQ delights like a cheeseburger or cold refreshing beverage, then Willis’ new invention could become the next party trick.

The Die Hard actor could probably use a few laughs after having a difficult month. Willis and ex-wife Demi Moore reportedly took their youngest daughter, Tallulah Willis, to rehab for cocaine and alcohol problems. The 20-year-old fashion blogger was allegedly given an ultimatum by her parents that coerced her into the stint. A source revealed, “Tallulah was pretty much given an ultimatum. Her parents were about to take away everything from her.”

Sources also revealed that both Moore and Willis have frequently visited their daughter at The Meadows treatment center in Wickenburg, Arizona, where Tallulah has reportedly been recovering for the past few weeks.

Willis is currently out promoting Sin City: A Dame to Kill For, the follow-up movie to the 2005 original Sin City. The much-anticipated Frank Miller/Robert Rodriguez crime thriller is slated for an August 22 release. The film also stars Mickey Rourke, Jessica Alba, Joseph Gordon-Levitt, and Josh Brolin.
