My younger sister, my mum and I where watching a kids program about arts and craft. The host motioned the so-called "Doodle Draws", which contain the materials for the current craft project on the show. Using our extreme maturate-ness, my mum and I went through the obvious jokes (Wanna see my doodle draw, He sure has a lot of doodle draws, e.t.c). Anyway, some time later in the show the Host mentioned that "This is a great box to put your bits and bobs is" or something to that effect. All my mum and I did was look at each other, not saying anything.
So long story short, I hope the word 'Doodle' has the same type of double meaning as the one I know. Because otherwise this story isn't funny.
