There are a lot of different variations to those. Google "atomic buffalo turds", "ABTs", "atomic dragon turds" etc.
Personally, I'm not a huge fan of cream cheese in them, it's kinda pedestrian. Consider pairing that with a more interesting cheese, like a gruyere, raclette, emmenthal, saint andre, etc. And then consider the cheese and meat pairing with something that will complement that, such as a sliver of fig, dried fruit, dried apple, etc. And then smoke that bastard in a smoker (if you have one) low and slow.
If all of that seems like a PITA, another popular variation is to stuff with bulk sausage or some other meat filling, as well as some cheese. You can take a sliver of cheese, wrap in sausage, stuff in jalapeno (or other chile), wrap in bacon, and poof.
Or, if you really want to fuck your guests over, make one of the poppers stuffed with Bhut Jolokia/Trinidad Scorpion pepper and unfortunate eater gets a prize. Like a burned out esophagus.
Enjoy!
