This is probably illegal to post, but I live dangerously and it's pretty funny. The visa application is all online for US citizens. It's pretty handy and the only quick and straight forward part of the whole process. You can save it half way through and finish it later. This section asks "Do you have any children?" Underneath it states "Don't have the information on hand? Click here to save your application."
This just struck me as funny as it implied that you might have to go check somewhere to see if you have any children or not. Well, I was amused. And it was a lot of effort to get the picture of the question on here; totally worth it.
