Well, that's certainly one idea for a landscaping business.
Smart Thinking: Weed Whacking While Riding A Unicycle

Because multi-tasking comes in many questionable forms (I cut my nails while driving and just leave the cuttings where they land), this is a video of unicyclist Mike Taylor using a weed whacker while riding his cycle. The video also includes footage of his unicycling partner Marie Schlenker performing some tricks without garden tools. Now I know what you’re wondering, and yes, you should definitely try this at home. I’m going to do it this weekend, except add a blindfold and a chainsaw to let Mike know who the real king of extreme unicycling is. “Should I have the hospital on speed-dial?” Just call ahead and tell them to send an ambulance at 2PM sharp — and bring blood.
