No, I didn’t. I don’t know who teaches people that commas represent small pauses in speech, but they’re not helping.

That’s what the ellipsis is for. If you want to correctly do fake Shatner you do

“This… means… that, Mr. Spock”.

That’s where the comma should go, by the way. You use it to separate the vocative. I had to use a period in the incorrect sentence above just to avoid the redundancy with the incorrect ones splitting the verb from the subject and the object.
