The smartest dog

A structural engineer, an architect and a general contractor are all standing around arguing who has the smartest dog.

The architect says "Watch this. autoCAD, come here!" And his dog trotted over to the drawing table where he got some paper and drew a square, a circle, and a triangle, with no sweat.

The engineer then said "Oh yeah? Watch this, Structure, come!" and his dog walked over to a pile of sticks and reassembled them as a perfectly scaled replica of the Golden Gate Bridge.

The general contractor laughed at this and says, "Big freakin' deal. Backhoe, come!" And with that, the general contractor's dog shat on the paper, knocked down the bridge, screwed the other two dogs, claimed he injured his back while doing so, filed a grievance for unsafe working conditions, applied for workman's comp and then clocked out early on sick leave.
