Yeah, the tell us a joke one sounds pretty daunting...I read about it on the Wannabe Interview section on this site. Apparently it's quite a favourite of Air Atlantique...
Pretty difficult one for me...I love to hear a good joke, but I am rubbish at telling jokes in a situation like that...

Ah well, I'll just have to impress them with my amazing flying skills...(Not that I have any...yet.)
