Quoted from ThePinballCo-op:

Oh man, Jurassic Park. I love feeding the T-Rex during the mode. That's still the greatest shot in pinball for me. It's timed 30 seconds so you have to be careful with the ball but also speed up. If you have the shaker motor on, you can feel the whole place rumbling as the T-Rex stomps around waiting to be fed. And then when you hit a PERFECT side flipper shot and hear the metallic "clink" as you place the ball in front of T-Rex and you watch him eat the ball. Oh man, what a feeling. You get a few seconds to celebrate that shot as the guy in the background yells out "nooo! no no no no no!!!!" Such a great moment for any player. That's my favorite shot/adrenaline rush in all of pinball (so far) and nothing else comes close.
Another great adrenaline rush for me is when Jurassic Park is in multiball mode, you spell CHAOS and then get the jackpot. The game yells out "JAAAACKPOOOOOOOT" and the music/sounds to accompany it is so awesome. And then when you continue that mode and you are able to feed the T-Rex for the Super Jackpot..... what a RUSH that is! And then the multiball ends and that awesome music starts playing to let you know you accomplished a great feat in the game. No time to celebrate the chaos but still awesome.
Another great rush is for Dialed In, when you are in a mode and you hit the big bang. That's awesome every time, and if the ball happens to fall into the sim card hole right after..... WOOOOOOO!!
The first time you start multiball on Metallica. I like how it gives you a moment to understand what's happening in the game, and then the guy gets zapped as he flails around. Very cool and I remember the rush I used to get from that.
To a lesser degree, the +million point shot during multiball on Whirlwind. Hitting it is great but no real time to celebrate, but I love the celebration and light show.
Also Alien pinball, when you get the mode where the machine basically turns all the lights off and someone yells out "WE LOST POWER!!" and then the sounds of some monster coming after you, followed by a quick multiball out of nowhere with the lights simultaneously coming back on. (this is how I remember it... it's been a while).
