Arn and Ole were surgeons in the ring. They truly epitomized tag team wrestling as heels - cutting the ring off, work on the one man, build towards the hot tag, etc. They were not flashy, they were not over the top - but they were DAMN believable. They both cut promos, they both worked in the ring, and they're both legends now.
Jack and Funk, similar to another Spam Zone thread, were one of those fashionable, "thrown together" teams. These two were teamed up to oppose the New Age Outlaws for a short time, and the tie that binded them was their Hardcore History. They were a well built temp-team designed to get the Outlaws over as a legit team. But Funk and Foley worked MUCH better as enemies rather than friends.
