An example of spontaneos wit.. Ed Trickett was performing, and the lock on the mike stand was not tight enough. That allowed the mike and the boom to slowly drop down. He pushed it back up, and it did it again. Finally, he asked "Does anyone ever water these things"?

Another time he was about to take a break and he said "Take it Ed." then he hit two wrong notes and said "Give it back, Ed."

On the other hand we have John Kerry who couldn't be funny because he totally lacks the equipment.
In other words, if you can do it, do it. If not don't try.

Seamus, you have the talent to entertain a performer who has heard it all, and I still enjoy your performances. You are a man who has it all, wit, songwriting and storytelling,
