How can you get the taste of dish soap out of your mouth if you swallow it?

Drinking coffee would probably be very effective. If you are not a coffee drinker, any other flavor will help to overcome the residual taste of soap.

Dude, I have had soap in my mouth before, and you either wait for it to get out on its own in a few hours, or just chew alot of gum, anything else won't work, and make sure it is some strong gum.
