I'm not sure, but the first pic doesn't really look like she's being tickled. The second pic is great, I like the shirt, nice find, thanks for posting.
In Woody Allen's SCOOP Johansson is participating in his magic act and she whispers something to him, and he laughs and relays to the audience "She said Please don't tickle me!" It was cute but anyone (like me) hoping it would lead to something was disappointed.
Yeah, I KNOW it was just a scene in a movie and doesn't prove anything but I thought it was amusing anyway.
