Took this exact type of shock with a board from a Wyse 50 terminal. Was carrying the board over to the solder station and the board flattened into the palm of my hand. It shocked me for about 5 seconds and the legs of the cap fused into my palm, I was jumping around trying to shake the board off (much to the entertainment of my coworkers).
My palm looked like I got bit by a vampire but since healed up.
