Eating tacos, burritos and enchiritos while trying to nail that ball with your 3 wood is perhaps the most daunting challenge of all. It is however very easily achieved if you are prepared to do a little work beforehand. Simply throw all of your foodstuffs and the contents of one (1) can of your favorite beer into a large blender and blend the ingredients for 2 minutes on high. A chunky yet liquid vomit-like consistency will signal that the mixture is ready. Pour this liquid food of the gods into a large bottle. Next, you will need a long piece of clear plastic tubing which can be purchased from any hardware store. The diameter of the tubing is left up to the reader to choose,
but it should be noted that large diameters have increased taco-liquid throughput and require less straining when sucking. Simply attach your bottle to your golf bag with some tape, stick one end of the tubing into the bottle, wrap the other end around your neck once and shove the opening into your mouth. This way, your arms are free, and you can nail that ball while sucking down a taco and a beer"
"The only drawback with this method is that your playing partners can pull hard on the tubing that is wrapped around your neck, causing a mean slice or in severe cases, death through liquid-taco inhalation. The number of deaths due to taco inhalation rose last year to 12. (source: AMA, Martinez, Lopez et. al. Nov. 1997) However more people die every day on our roads, so this figure shouldn't worry you."
Alternately, you could get one of those cigar holders to put your burritos in between swings. One thing the burrito could be doing is causing your swing plane to flatten out especially if swallowing at the same time, as the epiglottis can cause the adductor group to affect your abdominus rectus group, affecting posture and causing your deltoids to contract, which obviously would flatten your swing plane out. One exercise to remedy this would be, if you must eat and swing at the same time, put extra hot sauce on the taco, and try to keep a steep enough plane so that the sauce doesn't drip out. You'll kill two birds with one stone, actually--no sauce on the shirt, and a steeper swing plane.
If all of this seems like too much hard work, you should perhaps consider other foods and their delivery methods. ie: Meatballs, and slingshot, the most effective way your golfing partners can deliver an intact meatball into your open mouth without:
a) killing you
b) causing blindness
c) choking you
d) causing you to hook the ball (this is *very* common!)
