The ukulele is not on my list of "Things That Are Cool." However, I may have to rethink that after listening to a rendition of "Bohemian Rhapsody" played on one. Okay, the instrument still probably won't be on that list, but this version of BoRhap just might be eligible.
Note: the guy pictured above is not the guy playing BoRhap in the link. I just found this picture and thought it fit.
