"SETH!"

I've decided I need a bullhorn that bellows,"SEEEETHHHHHHHH!" We went to the grocery store today, and I can't count how many times I said his name.

"Seth, don't climb on that."
"Seth, get down."
"No, Seth."
"Seth!"
"Seth, put that back."
"Seth, leave your brother alone."
"Seth, come stand by me."
"Seth...Seth!...SETH!"

Maybe I need a cattle prod instead.
