When you catch someone staring, smile wickedly, lean over and stage-whisper, “You know the best part? If I press this button here, it can double as a sex toy.” and then laugh heartily and roll away.

My uncle B. used to have a motorized scooter and we used to climb on the back of it when we were at the mall or on long walks or whatever so that he’d have himself and four or five kids all hanging from him and one of us would always be yelling “Faster, make it go faster!”
Aw, rest his soul.
