My pick would be SummerSlam 1994, yes there was some silliness with the whole Undertaker vs Undertaker angle, and to boot you had George Kennedy and Leslie Nielsen playing their Naked Gun characters to help with the whole Undertaker case (I'll take this anyday over that nonsense with the 3 Stooges and Santino Marella - a segment that did not feel natural at all). But to me I didn't mind that at all, any match with the Undertaker is something I love to see. It also didn't hurt that you had an epic steel cage WWF Title match with Bret Hart and Owen Hart. I'd say it's one of my favorite matches ever with Bret and it was great to see him continue to shine in his second reign as WWF Champion.
Diesel and Razor Ramon's IC Title rematch with the late,great Walter Payton in Razor's corner was classic. It also set the stage for Shawn Michaels and Diesel's showdown at WrestleMania XI months later. To all you modern-day WWE asskissers, take note this is when the WWF knew how to commit to telling the fans a story, even if the product was not at its best during some of these years in the mid-90s.
Hell, even some of the lesser profile matches like The Headshrinkers vs IRS and Bam Bam Bigelow had great entertainment value. Anytime "The Million Dollar Man" is involved in something, I love it. He even made the Tatanka-Lex Luger sellout angle tolerable. Ted DiBiase was the victim of bad timing in my view when it came to his managerial stint in the WWF.
In other action you had Women's Champion Alundra Blayze fending off Bull Nakano and Jeff Jarrett beating Mabel. Granted those matches may not be as memorable to some, but with the previous matches I mentioned anyone in my age group that remembers this event as a kid, is hard pressed to argue that this was not a great SummerSlam.
In my view, 1994 was a very underrated year for the WWF. However, I look back on it fondly and am grateful to have been a fan during such a time, especially when you saw how you had so many great performances from wrestlers like Razor, Bret, Owen, Diesel, and Shawn to name a few. These guys had big shoes to fill with so many legends who had left the company to other ventures.
So yeah, I've ranted enough, SummerSlam 1994 is probably the pay per view that I would put out there as my snow/sick day event to watch. Seeing as it was also the last ever WWF pay per view appearance of Randy Savage (RIP) as well.
