Coordinate Geometry, a la Shmoop. Alvin, Belinda and Cletus do not get along.
- 00:13
In fact, all three have restraining orders against each other.
- 00:21
Best not to ask. Let's just say that not everyone should be allowed to own a paintball gun.

and he is at point C. However... these three can't be trusted to

If there are 5 yards between Belinda and Doogie, how much distance could be between Alvin and

...so if Belinda and Doogie are 5 yards apart, Doogie must be either 5 yards closer to Alvin
- 01:33
or 5 yards further away from him. Looks like Doogie is 12 plus-or-minus 5 yards
- 01:42
away from Alvin... ...which is either 7 or 17 yards.
- 02:00
Hullo, Answer "E." Good luck, Doogie -- you might want to consider

wearing an athletic protector. You don't want to

catch a paintball in your... area.
