You are clever. So clever. Not in the traditional academic sense, but in the Bart Simpson sense. First you spray-painted this on our shed, and at least 10 others on our street:
I bet Mike is with his friend, Ben Dover, at the tavern down the street.
Your comedic intent was so subtle in this first effort that I actually had to point it out to my husband. Lucky for him, my sense of humor is not unlike that of a 12-year-old, so I can often interpret the deeper meaning in these complex pieces of art.
Perhaps you sensed the possibility that your creativity may go underappreciated, because you took a much more blatant approach with your second installation:
Seriously, Kevin. Enough already.
I cannot wait to see what you come up with next. Please don’t touch my car.
Banana Wheels 
Oh man. You need one of those movement activated spotlight things. Or a movement activated video camera. That way you can track the kid down and spray paint something on his skateboard like, “My mom is always right.”
That is fabulous. But, yeah, hope he doesn’t touch your car.
There’s a road here called B.R. Reynolds Dr, and someone ever so tiny and subtly put a U and a T so it says BuRt Reynolds Dr. SO FUNNY.
