NOFXmike, let me explain a little about breasts.
Apart from in a certain genre of films, breasts
move.
Jumping up and down in a
dirndl signing beer songs could therefore be a serious risk to health (e.g. black eyes) and safety (public).
Especially if your dirndl isn't a crew neck one.
Or doesn't have super-dooper nipple-flattening fabric (you could take someone's eye out).
Throw a cracking pair of bangers into the equation and frankly that's a potential death trap.
Table for Sat in the Hofbrau? Death unlikely.
Dirndl without a bra?
Hmmmm.
