Is someone trying to tell me something..?

I received a mystery parcel at the weekend.  Without any sign of who it was from or why I had recieved it, I got 

a set of bodyfat calipers.  Now, these are all well and good but slightly confusing.  They retail at around a tenner, so they're not a promotional item.  I don't think anyone out there would send me a set as a gag because (1) I'd be tiresomely technical about the different skinfold-sampling protocols and my preference for the Jackson & Pollock four-site method as being a pleasing harmony of accuracy and practicality, and (2) I'd cry. 

On top of the bloody seal, it's all a bit much.
