THIS WEEK: Fools, border crossings, weed vs. your heart, bikes on BART, and an easy way for SFist Answers to make millions.

We took our title this week from Yueben Duped from Los Angeles (whatsmatta, no "answers" column in LAist?), who asks us:

Hey, what's that thing that a jester wears called?

I pity the fool who doesn't know that thing (belled cap, etc) is referred to as a "motley."

CG asks:

Do you know how I can get a copy of the controversial comic that showed people how to get across the Mexican/US border without dying. I believe it was put out by the Mex government.

Well, on an official level, I think you can get these things from your local Mexican Consulate. However, here it is on a Web site, for those of us who prefer to not get out of our chairs (a.k.a. SFist Answers).

Our very own SFist Co-Editrix Rita asks:

Why are bikes not allowed on the first car of a BART train?

Hey, Rita! According to the super-duper-awesome BART customer service department, the operator of a BART train, who is always in that lead car, needs to have his movements unhampered in the case of an emergency. A bicycle would very likely get in the operator's way should something unfortunate happen and the operator is called into action. A folded bike, however, is okay, as those are classified by BART as "luggage," not as a bike. Ride on!

Pappyklem asks:

I am trying to find out the effects of marijuana use in cardiac patients. I know cigarettes are definitely harmful, but does the smoke inhalation of pot affect the arteries to the heart in the same way as cigarettes? I have been trying to find info on pot for Cardiac patients for over a month, and have found nothing, so I was hoping maybe you could help me out, or refer me to a site that can.
