You use the zoom way too often. It's supposed to focus vision to provide a surprise when something comes up on screen or make you look closely at the subject.
The fade to the next clip sometimes feels too noticeable. I would make it a straight transition.
(Unobtrusive) music in the background really helps smooth the viewing experience for a montage. Cutting the music can make the viewer pay attention at a specific moment before you put it back.
Pausing for the memes gave the wrong effect. Slow down the video if it provides the proper emphasis (like at 0:48 or 2:09), but at least make them smaller and placed in some other part of the screen where it won't cover up the action.
I really like the video. You've got a great sense of humor. I'll be subscribing!
