When I was a kid, and in someone else's garden (e.g. one of my schoolmates, my Gran's etc.) when nobody was looking I used to take the heads off a few daffodils. Then I'd take some dandelions, cut them so they only had an inch or so of stalk, and pop them on top of the daffodil stalk. The dandelion stalk fitted really well into the daffodil stalk. People used to say how well developed their dandelions were - I never let on... until now! Ah, the innocence of youth with too much time on his hands and an overactive imagination...
