I'm Stuck

We have a toy that todd and claire have gotten their arms stuck into. A simple pull and they were out. A ball goes down a funnel into one side and a fan throws it out the other side. Rachel dropped a pen into it and decided to fish it out. She kept on pushing until she got her knuckles past the bend and couldn't be pulled back out. She brought it in and said "I'm stuck." It took me 10 minutes to disassemble it to get her hand out.
