you see 'nivo' the Dr
was trying to see if his bro's Mooney was faster than his own Bo so he wound the Mooney up & sent the needle right around the dial
As for the red thing hanging from what appears to be the Pitot tube? well that's actually a deflated red ballon from the night befores church party, it's just lying there on the ground, then again it could have been a coloured proprolactic (not too sure on the spelling & I ain't gunna check either!), used of course, but then again it's a Catholic church right?
Oh those Mooney boys, would you let yr daughter go to a church social with them?
p.s.........yes well spotted Nivo
