Right? Meet FO and FB in ops. FO - "just to let you know it's my first leg post IOE." Great.
FB - "I've got 40 hrs." Oh, that's even better. A grand total of *1* trip post IOE between the two of them. Me - "I'm not sure how this is going to work out. I normally rely on you guys to keep me straight." ;-)

At some point everyone's an FNG.

We had a blast laughing to and from Rio. Turns out the FB and a bunch of time on the 777. I told the FO (he and FB were buddies) - "ask him. He'll tell you, it's about 95% the same as the 777. So if you get confused just revert back to the 777 procedures and you'll figure it out." FO - "I don't have any 777 time." I ask FB - "it's true, isn't it?" FB turns to the FO - "he's right. It's very similar to the 777." FO - "I don't have any 777 time." Me - "well pretend you do. What do you think you'd do then? Just do that." FB's laughing - "listen to him, he's right!" FO's got this 'WTF, you've got to be kidding me' look on this face.' We're taxiing out. FB's laughing - "I love you man!" Fun times.
