leave me alone

As the internet becomes more and more ubiquitous, its important that we develop enough ways to politely excuse ourselves from conversation, less we get overloaded.

So I present to you, the following little known, "I can't talk because" emoticons:

There is the aforementioned "I have a cheekful of food":
:-Y

also, "Can't talk right now, at the dentist getting my teeth cleaned":
:-Q

also, "Can't talk right now cuz I'm trying to pick my nose with my tongue":
:-J

also, "Can't talk very well cuz I had a minor stroke and the right side of my face is paralyzed":
:-L

and finally, "I can't talk cuz I'm in that Twighlight Zone episode where the boy with magic powers attaches that metal plate over his sister's mouth":
:-[]
