Gallagher stopped by The Penthouse over on Real Radio today, so we decided to have him show us how to properly smash watermelons!  

I was the lucky person that got to film watermelon flying everywhere.  I'm a mess, but I got the shot!

Here's the video!

Don't miss "Gallagher's Last Smash Tour" this weekend at The Palm Beach Improv.
