I think I said that about seven posts ago and I didn't go to a fancy lawyerin school.
Oh, you said something? I didn't notice...
Like I said, I suspect they will change some letters and colors around and repost it at some point.
The problem is that the billboard loses its humor and purpose if people can't recognize it as a reference to Texas A&M. So they have to include enough elements so that the viewer recognizes it as a reference to Texas A&M. And if you include enough elements so that the viewer recognizes it as a reference to Texas A&M, then it's reasonable to conclude that there might be consumer confusion as to the source of the billboard, meaning that the viewer assumes the billboard is promoted/endorsed/created by Texas A&M.
Basically, it's not a matter of whether your trademark is exactly like someone else's; it's a matter of whether your trademark is similar enough so as to cause consumer confusion.
