Personally I don't think this is funny at all.  In my opinion they're just setting themselves up for trouble in the future.  If they keep treating the puppy like that and won't leave it alone when it wants to rest then sooner or later it may well snap back at them and cause somebody an injury if it sinks its teeth in.  And what happens then?  The poor dog gets put down, having been labelled as a "dangerous dog" and the victim could potentially get seriously injured - maybe even sustaining life-threatening injuries, depending on the severity of the attack and the location of the wound(s) - and for what?  Because some idiot thought it was funny to keep disturbing the dog when it wanted to rest just so they could get a laugh when they posted the video on YouTube?  They won't think it's funny if the dog does eventually snap, especially if it's a kid that gets mauled as a result!  If people are going to behave this irresponsibly with no thought as to the long-term consequences of their actions then they shouldn't be allowed to own a dog in the first place.
