Ok. I was actually helping my neighbor dispose of his own body in the backyard. But yes, fecal suffocation is actually quite common; especially when I'm working with other people.
Warik,
As you are well aware, the average human's intelligence decreases exponentially as they congregate with one another. This leaves you with an extraordinarily large window of opportunity to commit whatever type of atrocity is suitable for this particular situation.
From your posts, I have gathered the notion that ignorance and stupidity, even if they are one and the same, irritate you to great lengths. Therefore, this coming meeting is sure to set off the hostile murderer that I know lies deep within you. This is a great thing which should be embraced if you are to leave a great impression (or cavity) in these people's brains.
I will assume that you are gathering in a library or similar type setting, where people may be lurking about. You may have to assume a covert mentality if you are to avoid possible jail time.
First, act as if nothing is awry and begin your meeting as planned. Say your bit, and when the next person begins to speak, knock his/her teeth out with a claw hammer (wear a tool belt). As the others begin to get worried, tie the toothless one up with some rope (keep it in your tool belt) and tell the others that if they comply with you and don't make a scene, that they will get out alive (obviously a lie, but humor them).
Tie them all up and crush the toothless ones head in with your hammer, making sure that he/she dies and brain matter flies out onto the others. Now, the others will be making quite a ruckus, so it would be advisable to duct tape their mouths shut.
Two to go. Hobble one of them with your hammer and stab the other in the eyes with a pair of needle-nosed pliers, making sure to remove the eyeballs as you pull it out of the sockets. Fill the emptied sockets with firecrackers (the power of said crackers is up to you) and light the wicks. If you used sufficient enough power, the person should now be dead, and their brain should be smoldering and leaking out of their ears and eye sockets.
One left. For maximum effect, I would take the simplistic route and just beat him/her to death with your hands and feet. This is the most personal route to take, and also, in my opinion, the most enjoyable. Alternately, you could practice your acupuncture on him/her using 6 inch spikes, or you could use that in combination with the old fashioned beating. Either way, it is up to you.
If these methods don't appease you, just ask and I will try to supply you with some alternatives. Anything for a potential multiple murder.
Happy homicide,
