I started off by drawing a rainbow on one, 'cos it was colourful and not difficult. But a bit later, I remembered these earrings, and, well, there were some spare bibs left... The result was one with <BODY> at the top of it and </BODY> at the bottom of it.
There was only one person there who actually got the joke, but fortunately it was the baby's mum. She asked if I was going to put anything in the middle, but I couldn't think of anything suitable, so I was just going to leave it blank... until I was visited by the Bad Pun Fairy. I added some paragraph tags, and between them, a green dot symbolizing a pea.
