The narration in the beginning really cracked me up. It's really dry and silly so that made me laugh!

Same with the first shot of the 3 guys, it's funny in the beginning but it does drag on too long i think. The audio is also pretty low so i had to turn it up to hear what they're saying (which really really was not fun when they suddenly started screaming after the other guy came back....That's where i stopped watching cause my ears got destroyed :( Next time, check the volume differences and see if you can get better equipment so the audio doesn't freak out with higher volumes!)

I think the idea of the long shot was to show how incompetent the guys really are, correct? This can be a very funny premise but i would advise using more shots, different camera angles and more physical "acting" by the characters.
You could show them fumbling with equipment for example, or just more shots of them walking through the place where they are.
Zooming out will also help with the punchline when the other dude comes back floating. Because the shot is so close it took me awhile to realize he was hanging in the air!

Keep it up and you'll get better and better! Hope this feedback will be of some help :)
