It depends on what you mean by "stuck in a conversation".
If I were in a conversation I didn't want to be in, I would give the situation some time, but if it kept dragging on I would make up some reason to leave.
If I were in a debate and I was losing, I would probably try and find a better way to explain my point. :)
