I’m fixing…

A young fellow and his girl are parked in a lover’s lane that runs along a river. The guy wants to make love, but the girl is afraid somebody will come along and see them. They decide to do it under his Dodge 4 X 4 pickup with oversized tires and lots of room under.
A few minutes later, a county deputy pulls up and says, “Hey, what the devil you all doing down there?”
The young fellow being in a full rut doesn’t even look up, but manages to say, “I’m fixing my muffler.”
The deputy says, “Well, son, you shoulda been fixin’ your parking brake, ’cause your truck just rolled into the river.”

You don’t know..
