I always wonder how many idiots have been denied entry because they were dumb enough/drunk enough to think it'd be fun to tick the wrong box on that form.
I also love how under the Paperwork Reduction Act they have had to estimate the burden of filling it out, but seemingly not consider whether or not is serves any actual purpose to ask those questions in the first place.
