You should second mortgage the house, buy a barn full of them, and be the North American distributor for ukulele egg slicers! Sell them for, like, two for $5.88. You'd make a killing, lancemanion.
You could lord over them since you have them all. "You wanna ukulele egg slicer? Is that what I'm hearing? Well, lets just say dinner's on you--what's the ritziest joint in Bentonville, AR, anyhow?--and you treat me like one of the family and I'll see if I can't come up with a few for you, Sam Walton, Jr. Capice?"
One caution: you'd have to act quickly before this currently fading wave of uke popularity goes completely in the crapper because the plastic recycler would give you a nickel per dozen for them. The next ukulele wave isn't due until around 2099, and something tells me your grandkids aren't gonna want to frig with these things.
