Hmmmm, well I'll be stuffed!
To think, all these years I just assumed they were called "Teabaggers" because,
1. they are so easy to stir
2. once placed in water they seem to turn it murkey brown in hue!!
3. (just like the ones on the shelf in the supermarket) even though they are screaming for your attention in their brightly clad colours, you still tend to walk right past them without noticing !!
