So many bad ones!
T-Bone Suplex: Shelton Benjamin (weak)
F-U: John Cena (weak also)
Temple Grind: Sgt. Slaughter (his pro-Iraq heel finisher that he used in conjunction with the Camel Clutch as his finishers - this one sucked b/c he sat the guy upright, and grinded his middle knuckle into their temple - and people submitted from it!!)
The Worm: Scotty 2 Hotty (lame and weak)
Pump Handle Slam: Snitsky
Dancing Punches with Wiggling Knee Drop(??): BG James/Road Dogg
And for the old-school folks:
The Battering Ram: Bushwhackers
Three-Point Stance: Hacksaw Jim Duggan
Shake, Rattle & Roll: Honky Tonk Man
Samoan Drop (a/k/a "Papoose To Go" - according to Bobby Heenan): Tatanka
Discus Punch: Kerry Von Erich
I will say this, though - I know the Heart Punch got dogged on this post, but I think it can be a credible finisher for the right guy. If the announcers and wrestlers sell it properly, it can be put over. Hell, even a stiff like Snitsky or Heidenreich could look borderline credible with that move. OK, maybe that's too much of a stretch, but I stand by my opinion of the Heart Punch nonetheless.
