Lumpy Rutherford was no mental giant, but the man who played him turned out to be a financial whiz. In the years after Beaver, Frank Bank became a highly successful municipal bonds broker in Palm Springs, California. His wealth didn't ruin his sense of humor or nostalgia, however, and he was more than happy to rejoin his cast mates for Still the Beaver
and make a cameo appearance in the 1997 feature film remake of Leave It to Beaver
Clarence "Lumpy" Rutherford is one of Wally's best buddies. Lumpy's a bully and is as thick in the head as he is around the waist. It's no wonder he turned out the way he did, as his father Fred Rutherford, who works with Ward is a major blowhard with enough annoying characteristics to drive a civil man like Ward to the brink of insanity.
