George Matthews who plays the brutish, lout of a husband was usually cast as a big, dumb henchman, worker,side-kick, etc. in his roles.  He was in a classic "The Honeymooners" episode where his much smaller and meek looking friend is holding a pool table while he was somewhere else and Ralph and ED Norton come in and take the pool table and the meek guy starts saying that his friend."Harvey", I think was the name of the character George Matthews was playing got the table before they did and he was going to start trouble with Ralph if he didn't let them have the pool table.  Well, Ralph thought the friend was a small wimpy guy like him and starting mocking him and "Harvey". Of course , when Harvey shows up and Ralph is shocked to see the big tough Harvey he starts "ahummanah, a-humminaing" and Ed Norton makes things worse by challenging Ralph to beat up Harvey in a fight at the local gym.  I guess with a face and voice like George Matthews had he was pretty much typecast in those types of roles.  I also agree with the comments about the wimpy piano student.  It wasn't very believable that he could fight his way out of a paper bag, much less the husband.
