Aw, I miss Speed.
Let's see, one of my favorite lines was from "Entrance Wound" (I think):
"Never go naked on the hotel bedspread."
I think the banter btw Speed and Delko was at it's best in "Blood Brothers" when they were talking about finding the owner of the yellow Lamborghini Diablo and Speed asks Delko if he still knows that girl from the DMV. Then Speed tries to get Delko on the phone with her and he's all "Then I'm going to have to listen to how I never call." Speed's reply is classic (I think it went something like this): "Eric, you've got to take them out for a meal once in a while. You have to cultivate things. You're better than that. I'm dialing." then he hands Delko the phone. I laughed so hard.
Same ep when he and Delko are on the barge looking for the discarded airbag and he finds it, but has to yank hard to get it free. When it finally comes loose, it jerks him backward and he hits his back hard. He gets this pained look on his face and you can tell he's about to drop an f-bomb but it cuts to Delko.
I love Ryan, but Speed was one-of-a-kind.
