However, if Antonio isn't there, and Merl sees other dogs looking at him,
he pees and scratches the ground again to be sure they know what he's done.
Recently, Mitsubishi Electric Research Laboratories(Merl) researchers Amit Agrawal, Yuichi
Taguchi and Srikumar Ramalingam solved the extension of Alhazen's problem to general rotationally symmetric quadric mirrors including hyperbolic, parabolic and elliptical mirrors.
However, after he pees a bit the second time, if Merl sees his friend Antonio, he
takes off, runs straight at him, does a few quick play bows, and the two wrestle, bite one another with abandon, chase one another all over the place, often running over other dogs and nearly taking down some people.
