Drag racing on the Hoveround.
Where I grew up the towns beach patrol would occassionally make the rounds, checking for beach badges, making sure no one was having too good a time, that sort of thing.
Welllll...they got a bonanza one year, and found it in the budget to purchase some orange golfcarts, that had the brand name "Cushman" blazened across the front.
So, I'm hanging out on the beach w/ some friends. On the blanket next to use where 2 young guys who were "horsing around"
Suddenly, one of the guys said "Cool it Scott, the Cushman's coming."
For the rest of the summer, and all of the next, that was our tagline.
"Cool it Scott, the Cushman's coming"
It never failed result in high-larity.
