At a job interview

Me: so how many people do you have in your lab?
Interviewer: We have one part time technician and four students
Me: and what level are they at?
Interviewer: ah one is a genetics honours, two masters and Euen is doing his PhD
Me: is that Ewan McGregor?
Interviewer: *pause*, ah, Rogers, Ewan Rogers – did you have him as a demonstrator?
Me: (think to myself: where did McGregor come from?)
Me: No I know him from church

Suddenly 1.5 hours later, whilst casualy riding an elevator:

Me: Ewan McGregor! Ewan McGregor! Nooooooooooo!

Oh man how stupid I feel.

Incase you dont know Ewan McGregor is like a super famous actor who plays Obi Wan Kenobi in the Star Wars prequels.
