Okay, so what it sounds like is what we want
is a DEVICE that can deliver a message...
The Big Bang Theory Season 8, Episode 21
or a homing DEVICE
Breaking Bad Season 2, Episode 9
Now we just need to figure out
a delivery DEVICE,
Breaking Bad Season 2, Episode 1
Although it occurs to me, you may
have been employing a rhetorical DEVICE...
The Big Bang Theory Season 1, Episode 10
If I remember, Kirk will steal
a cloaking DEVICE from the Romulans...
The Big Bang Theory Season 1, Episode 14
