Crutchless Knickers Anyone?

Oh how naughty, but don't blame me, it's all down to my friend MOB and her suggestion for getting my own back on The Wee Git. I think it's a great idea, but it has just occurred to me that I'll have to go out and buy some if I want to stuff them in his unsuspecting suitcase! Now this would be fine for some of my younger Blogging friends, whose intentions might be said to be thoroughly naughty, but I'm a Grandmother.. What do I say? "Oh, I'm just buying them for my Daughter." Or do I just stuff them in my bag and try to get out of the shop without getting caught? (This brings vivid images of Grandma Giles, if any of you can remember that cartoon, she would definitely have been up for it.) I know there are some saucy ads in even the Hove local paper for "older ladies" who are prepared to offer a "good time", but come on, that's not me. (Sorry, Billy, not even for you :-)

So now I need more suggestions. How on earth do I get hold of the crutchless knickers without getting into a really embarrassing situation? In fact, where do I find them? It's rather a long time since I was out there, if you know what I mean, and I'm not telling you how long it is since I last had sex. This is turning into a rather more complicated exercise than I had imagined. That Wee Git has a lot to answer for...
