He might not have laughed, but that didn't stop Cliffjumper from noticing the clear humour in Optimus' voice, as well as the shiver when he'd tugged on the audial, but it was hard to keep his huffy expression with the Prime rubbing their faces like he was some sort of casseticat.

"Uhh... what? I suppose... I mean. Relaxed?" Frowning, more confused over what was asked than annoyed Cliffjumper nonetheless squirmed underneath Optimus' weight. Reaching up with his other hand he closed it about the other audial and gently pulled on both, stretching to be able to rub his thumbs over the tips with a thoughtful frown on his faceplates.

Basically, if Optimus' wanted to overload Cliffjumper in peace more times, he'd have to do something about those wandering hands.
