His big claim to fame is jumping out of a trunk naked -- and his parents couldn't be more proud!

We got a clothed Ken Jeong waiting to pick up his parental units Saturday at LAX -- very cool by the way -- where he said his mom and pops had actually seen "The Hangover" in all its glory ... and were watching it again on the flight.

FYI -- According to Ken, the plane version ... not as genital heavy.
