X-RAY Lines: Improv By Woody + Louise?
When Woody replies to Louise's statement "I have something important to tell you." with the line "Why? Have you seen X-Rays of me?" Louise cracks up laughing which makes me wonder if the line was a quick improvisation that caught her off-guard. Still laughing she then says "Yeah, I saw X-Rays of you!"
Louise shows her quick comic wit when after Woody then says "I fail to see the humor." she replies "Well, ya haven't seen the X-Rays!"
