After I'd convinced my brother about this odd lyric and he was busy trying to convince someone else--they produced the liner notes and we were both red-in-the-face. The full verse was:
MacArthur Park's is melting in the dark all the sweet, green icing flowing down someone left the cake out in the rain I don't think that I can take it 'cause it took so long to bake it and I'll never have that recipe again Oooh, nooo! oh oh no no!!
