I know this is going to come across really strange, but I actually like this. Well, to be more specific, I like the premise. In other words, I like what it could have been, rather than what it is. Let's call it a missed opportunity and hit the restart button, this could be awesome.
If I may, here is a potential skit that could have played out instead:
Premise - Every video is to feature someone we could call "Joe" or "Jane", as in to represent someone who is from "real" life and they happen to meet characters from games - this is what I understand the setting of the videos to be from this one.
Set the scene, guy just relaxing and working out. Instead of having 47 talk, just have him show up. Guy working out wonders why this man is staring at him and tells him to bugger off. Show various items around the man working out that 47 looks at, try to imply possible uses as weapons. Have 47 keep showing up, not talking, in different "disguises", but its obvious that the man is bald and still creeping the man out. Finally, just as 47 sneaks up behind the man working out with like a piano wire, have the character from Assasin's Creed pop out of no where and do 47 in, then join a crowd of passerby or climb up a wall or whatever. Hopefully the implied would be that Joe Average is going to get it but with sudden delivery 47 gets it ... oh, and for added silliness if its felt its needed, instead of death by blade, use comedic death by cream pie and have the stoic Joe Average break into knee laughter. Could even do like a photo shoot type thing where its like a fan having their pic done with their star, standing over the pie in the face 47 with thumbs up or whatever.
Just an idea, could have went differently than say "Oy! I'm wearing your clothes!" *shrug*
