Puck from 'Real World' -- Sentenced to Daddy Classes After Domestic Violence Incident

Legendary "Real World" troublemaker David "Puck" Rainey needs to learn how to be a better father ... at least according to an L.A. judge -- who sentenced the reality star to parenting classes after his recent domestic violence arrest.

As we previously reported, Puck was busted on suspicion of felony corporal injury on a spouse or cohabitant back in June.

It's unclear exactly what happened during the incident, but it's likely his kid was present -- because Puck was charged with child endangerment and contributing to delinquency of minor ... in addition to domestic battery and corporal injury on a spouse.

Puck struck a deal with prosecutors yesterday -- in which two counts, child endangerment and corporal injury on a spouse, were dismissed. In exchange, Puck pled "no contest" to domestic battery and contributing to delinquency of a minor.

The judge sentenced Puck to 4 years probation -- in addition to a 52-week domestic violence counseling program and 52 parenting classes.
