Ha Ha Funny, Not "ha ha" Cow Barrier

For some reason I got it in my mind that it was important to develop some landscape architecture jokes, so here's what I've got so far:

How many landscape architects does it take to screw in a light bulb?
-How many?
-We have a very qualified electrical sub-consultant for that.

What's black, white, green & striped all over?
-What?
-A Peter Walker landscape.

What do landscape architects call a Brazilian wax?
-What?
-A Roberto Burle Marx

Why did the landscape architect cross the road?
-Why?
-To get to the other bulbout.

Your momma's so fat she can't fit in paper space.

Knock, knock
-Who's there?
-Kobori Enshu
-Kobori Enshu who?
-Enshu glad I gave you this borrowed view?

wakka, wakka, wakka....
