A car leaves Avon, Indiana at 2PM, driving North/northwest at varied speeds between 55 and 125 mph, stopping an average of 5 times to get gas for about 15 minutes per stop. Keeping mind the 1 hour time slip between EST and CST, when does he get lost hear River Falls, WI and stop to call Talula for help?
hehe
This one's an inside joke. Luckily, I never got stopped by the cops!

Actually, I was taught that an angle was 2 noncollinear rays with a common endpoint. If they were collinear, then it would be a line, by definition. A triangle is the union of 3 segments determined by 3 noncollinear points.
Next question - where do parallel lines intersect, or DO they?

Speaking of getting stopped by the cops...
A highway patrolman was rushed to the hospital with an inflamed appendix.
The doctors operated and advised him that all was well.
However, the patrolman kept feeling something pulling at the hairs in his crotch.
Worried that it might be a second surgery the doctors hadn't told him about, he finally got enough energy to pull his hospital gown up enough so he could look at what was making him so uncomfortable.
Taped firmly across his pubic hair were three wide strips of adhesive tape, the kind that takes everything with it when you pull it off.
Written in large black letters across the tape was the sentence:
Get well quick .... from the nurse you gave a ticket last week!

Depending upon your definition of parallel, they intersect when on the surface of a sphere. Of course, thanks to Einstein we can be fairly sure they'll also intersect in the presence of a gravity well deep enough to warp space/time.
I don't think either answer is the one you had in mind though. Heh.

StefanIsMe defined the triangle just as the set of three points (non-colinear), Paolo as including also the points on the segments connecting them (the "frame"), but some (like me) think of the triangle as including all the points inside (the "sheet"). People who naturally think of "the triangle" as just meaning the "frame" are often surprised to learn that some others naturally think of "the triangle" as being the whole "sheet", and vice versa. (Mathematically, of course you can define your terms however you like, call the frame the "triangle" and the sheet the "interior of the triangle", or call the sheet the "triangle" and the frame the "border of the triangle".) I wonder if there is any psychological significance to the difference between "frame" people and "sheet" people.

I suspect it is true. Just don't ask Dan Quayle. Heheh

...Can parallel lines REALLY be INTERSEXED?

They are essentially a-sectual
