Hmm... I don't think so. Maybe if Arnold had a lower and slower voice he could sound a little bit like Sekto.
Sekto also puts a bunch of hissing and sissing sounds in words:
"Heads muhsst be freshss for thwenty ghrand."
I must say that Sekto sounds a lot like the Raisin. But they're both spoken by Lorne so... never mind.
