Has this ever happened to you?

Dude, the cigar is possessed! Either that, or my bro-in-law is! LOL!

It looks like one problem may be humidification.
The burn looks uneven. Could be due to the stick being at the top of the humidor and getting a lot of moisture and/or not rolling the cigars to get the dry side up. If the cigar gets too much moisture, it will swell up giving a tight draw. When the leaves burn and turn in to ash they dry out and expand, this expansion could be where the split is coming from.

Or it could be a Linda Blair Especial

I've had that happen on a cigar with a good draw and even burn. Just one of those cigar smoking type things that happen.

Bro' speak with fork tongue.

I bet his significant other likes that. heh heh!
