Twin seed or mutant?

I have one growing right now and I had one last year! I just posted about it yesterday in my grow log if you want to check it out! I attached a link if you want to check out the one I have growing right now.

The on I have now and the one you have appear to be joined together. I ended up planting mine as is this morning but the one I had last year was different. It was not joined together and easily split into two. I was able to get both of those to grow and the runt of the two ended up being fire!!! I will try to find a pic of my Capulator Burnie Mac that had twins last year. Someone did tell me they have spliced them with an exacto knife but I decided to not try it because you take a chance in killing both.
