No pooping in the yard

Last week GML4 decided to squat in the yard.  His mother spoke with him and explained we don't do that.  The next day during naps his mother heard the door open and went to investigate catching him in the act.  I then spoke with him and asked him why he would do such a thing.  His answer?  "I'm a Lamborghini and I'm fast." huh?  I explained that Lamborghini's use the toilet and he hasn't violated the lawn since.
