If you really want to impress the audience, keep a cucumber in your trousers.
Smile, and play through mistakes. Your average audience member will only suspect something is wrong if you stop and make a concerned face. If you smile and play through it, it must have been on purpose, right?.
I'd take that one step further. If you make a mistake, do it again, and again. The ear gets used to hearing it and it becomes inspired, purposeful improvisation. I do that all the time.
