Wilf-
Coincidently enough there is, but it will only help you if consumed in mass quantities. What is this miracle supplement you ask- beer of course! Consuming a significant amount of this supplement will leave you with the inability to coordinate heel-toe, and you probably shouldn't even put the key in the ignition in the first place. (Of course, there are other significant advantages to consuming this supplement, the least of which are your jokes become much funnier (at least to you any way) and everyone around you looks much better, especially the ladies)
And who drank more beer than Norm?
