At one point Bobby Denver refers to "braces". As an American he would use the term "suspenders".
The newspaper front page story exposing Bobby's trick for crying on cue is an extremely obvious manual cut-and-paste job. The uneven lines, changing paper shades and wrinkled surface make it clear that the individual articles were clipped from different papers and messily glued to a backing page. This is a candidate for Worst Prop Ever.
