#2 Pedro Morales (425 days)
Pedro Morales is most well known for his WWE Championship run in the company, and considering all of his achievements it's surprising that he isn't mentioned more frequently. With that in mind, it seems likely that some people won't realise that he actually had an impressive run as Intercontinental Champion back in the early ‘80s.
Morales won the title from Don Muraco in New York back in November 1981, holding on to the strap for 425 days, until Muraco won it back in January 1983. Morales always seemed to be a trusty hand when it came to long Championship reigns, and you could always count on the Puerto Rican star to put on top quality matches week in and week out.

As such, he should get a bit more recognition by WWE. We conclude with the most unlikely of record holders.
