classroom product placement

One assignment I gave my first year students was to make an advertisement (a commercial) in class. Today is the first day of presentations and the first one was of a bear and a man wrestling for salmon. Many of you might recognize the plot from this ad/video. I am disappointed that they copied the idea so completely - even the tin of salmon was marked "John West Salmon", but I like the effort they put into the preparation.

Below, is the bear and the bear threatening me.


So, I'm torn; the acting was pretty good, and the ad is undeniably funny, but should I give any grade to plagiarists? In watching the Youtube video, I see that my students used the exact script from the commercial.

remember: John West; they do their worst so you can have their best!
