Mhh, could've made a joke on how Aerith goes "MakemeaflowerwagonMakemeaflowerwagonMakemeaflowerwagon-That Flowerwagon you built SUCKS!" joke with her. As much as I love Aerith, that's her mostly said phrase.
I guess, but it wasn't really funny or anything. Plus it was Zack himself who started it. Tough it would be funny if I had Zack working on the flower wagon during his missions.
