Funny Grammar Error 

I was at the grocery store a few months back and saw this on the shelf:

Apparently, this is the generic brand of "I Can't Believe It's Not Butter." It must have taken a clever mind to come up with the store brand title, "This is not Butter, it's Butteriffic." Unfortunately, it's a prime example of a comma splice. The person who wrote this tried to join two independent clauses with a mere comma. Here's a few suggestions to remedy the problem:

-This is not butter. It's butteriffic!

-This is not butter; it's butteriffic!

I'm no grammar expert, but I know a run-on sentence when I see one. Anyways, I've tried this stuff; it's not so bad. (Observe the correct usage of the semicolon.)
