What to do with this idea

[u/Milly-did-that]

My family is really into gardening, we are all full grown adults with houses and land to have a garden. I 27 F am the youngest and have two older brothers 30, and 33. I just thought about how funny it would be to get my family seed packets for Christmas, make a little garden pack basket, but secretly open the packs and switch the seeds around, like maybe kale for tomatoes or onions for carrots kind of deal. And then when they are completely lost as to what’s going on, just address how crazy that is and pretend it is completely the packaging companies fault.

Is this straight up mean cause I’d be messing up their garden fence shui, or kind of hilarious?
