Rusty Stevens was so convincing as Larry Mondello, and this is his showcase episode. It's one of those "Mom has to go out of town, and can I stay over...."
episodes which clicks, thanks to some spot on writing by show producers Joe Connelly and Bob Mosher.
It's really a true to life story, because how many of us kids wanted a good pal to stay overnight and the stay was not always fun. Problems, problems!
Ward is doing the fatherly thing and cookin' up the burgers on the grill, all the while Beave and Larry slowly begin to have issues?
I agree with the last reviewer, the scenes with Larry or his mother (Madge Blake) are very funny, especially Mrs. Mondello whose husband always seems to be away on business and she looks like she's ready to scream! Larry also has an older sister (who we never see), also complicating matters for his short fuse mom. There are a lot of unexplained things in the Mondello household, which may have been a gag thrown in by the writers, or something to build on in later episodes. It was always a head scratcher.
Matters do change, and in the middle of the night, when Larry wakes up sick as a dawg, this due to all the candy bars he smuggled into the house and stuffed under his pillow. By the way, while all this is going on, poor Wally is put into a guest room and is kind of on his own, which may be a blessing in disguise.
Veteran character actor Frank Sully plays a cab driver, who was in tons of movies and classic tv shows, such as I LOVE LUCY.
And yes... Ward must have forgotten the hole Larry drilled in the garage wall in the last episode!
Don't stay up too late! And don't make a lot of noise! From SEASON 1 remastered Universal dvd box set.
