I'm sorry, but why is this any more tasteless than appearing to pull a bra out of a woman's clothing?
I can't help but think that this is really just more of the same.
Is it the association with stripping that bothers you?
The Bra Trick and Short Surprise type gags where done with tongue in cheek and a "naughty" bit of silliness not as an expression of sexuality let alone what most of the world views as "perverted" sexual expression . . . there's a lot of big bad redneck types that are scared to death of having their ear pierced let alone their nurple or things south of the belt-line. Then again, many of them are told that it's not a "Christian" thing (though the one assumed teaching about piercings found in the old testament, involves a man nailing his ear to a mans door as a symbol of servitude and to show his love and grace to said man, the "Master" placed a gold ring in the wound). . . far be it for me to point out the facts though. . .
The bottom line is that especially in the U.S. there are many that would take extreme offense to this sort of material, INCLUDING those that are actually "into" the scene (not that I'd know people like that).
ONE OTHER POINT. . . within the magic world's political base, the Bra & Shorts as well as Cards from Mouth, Mouth Coils, the Magic Ding Dong and a handful of other bits have all been seen as "blue" and "tasteless" and thus, not the sort of thing a "proper" and "respectable" professional would ever do. Such things actually degrade the public opinion of magic & magicians.
