If you think this is bad and the worst your kid will do, the yolks on you. Make him help you clean it up while explaining to him why he should not have done this. Scary how some have posted they would spank or beat him. I spanked my kids but not for stuff like this. 1st offense. Verbal warning and explanation. If this is a 2nd offense...then yes, I'd spank him and give him the verbal again while doing it.
