"They're real and they're spectacular" *still* gets a huge laugh at corporate events. Thanks Seinfeld (which I haven't actually seen, but I know the line).
Believe me. No one is as shocked as me.
The reason is because it's just a teensy bit naughty while also being completely clean. (The original line referred to breasts.) That goes over big with executives.
It's also why 50 Shades of Grey is the gift that keeps on giving. It's so mainstream that it's totally safe...yet everyone knows it's a naughty reference.
I wonder what the next everlasting naughty-safe bit will be.
