Lifting weights

Jack: Can you "spot" me while I bench press?
Laura: I can't lift those weights!
Jack: You don't have to. When I slow down and can't quite lift them all the way up, all you have to do is apply a little upward pressure to help me finish.
Laura: What if the weights get stuck on your chest and I can't help you?
Jack: Then you can call the cute firemen to rescue me.
Laura: In that case, I'll just sit on the bar right now! ("Sorry, Mr. Fireman, I don't know what happened!")
Jack: Don't make me laugh while I'm lifting weights. Here we go... 1 .. 2 .. 3 .. 4 .. uh .. 5 .. uh ..
Laura: Do you need help?
Jack: Not yet ... 6 .. uh .. 7 .. uhhh
[Laura freaks out and can't wait any longer and helps lift one side, tipping the weights, but we manage to get the weights up anyway.]
Laura: You asked for help, right?
Jack: Um, no, but thanks anyway. I guess we're done now.
Laura: Whew, I'm exhausted. Chloe, let's go downstairs and lie on the couch!

[A few minutes later...]
Jack: You could try lifting a few weights...
Laura: Yep, I'm going to get a really giant cup of coffee and lift that.
