It today's paper (September 23rd, 2006):

"Three-ana-half?" Dennis breaks a third of the a Ten Commandments on a good day? I've compiled a chart to analyze this based on what we know of Dennis from the comic strip. I'm guessing that Dennis is a Protestant, so I'm using the Protestant Ten Commandments(yes, there are different sets of the Ten Commandments depending on your religion. More Details).

Commandment Half-breakable Likely to be broken by Dennis
1. Thou shalt have no other gods before me. no No. Dennis has rarely or never mentioned any god.
2. Thou shalt not make unto thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water under the earth: Thou shalt not bow down thyself to them, nor serve them: for I the Lord thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me; And showing mercy unto thousands of them that love me, and keep my commandments. no Possibly, if toys, comic book heroes, or Santa Claus count as graven images.
3. Thou shalt not take the name of the Lord thy God in vain: for the Lord will not hold him guiltless that taketh his name in vain. no Maybe, but only if at an inappropriate time innocently repeating something he heard an adult say.
4. Remember the sabbath day, to keep it holy. Six days shalt thou labor, and do all thy work: But the seventh day is the sabbath of the Lord thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is within thy gates: For in six days the Lord made heaven and earth, the sea, and all that in them is , and rested the seventh day: wherefore the Lord blessed the sabbath day, and hallowed it. no No. Dennis doesn't work any day of the week if he can help it. If God says "take a day off," you can bet that Dennis listens.
5. Honor thy father and thy mother: that thy days may be long upon the land which the Lord thy God giveth thee. yes Yes. The only commandment that's guaranteed to be broken by Dennis.
6. Thou shalt not kill. no No (but wait- when's the last time you saw Joey?)
7. Thou shalt not commit adultery. no No. Girls are gross.
8. Thou shalt not steal. no Maybe, but I don't think so. Dennis seems to think a lot like the guys in The Gods Must Be Crazy: there is no property, and everyone has equal right to everything.
9. Thou shalt not bear false witness against thy neighbor. no No- Dennis is brutally honest and uncomfortably open about his neighbors. Ask the Wilsons.
10. Thou shalt not covet thy neighbor's house, thou shalt not covet thy neighbor's wife, nor his manservant, nor his maidservant, nor his ox, nor his ass, nor any thing that is thy neighbor's. yes Maybe- see "thou shalt not steal" above.

That's one yes, four maybes, and five nos. My guesses for the commandments broken:

Exciting bonus fact I learned: There are two different "Dennis the Menace" comic strips. America gets the kid in this comic, and the UK gets a completely different kid.
