I already looked on IMDB but it hadn't been updated and only had 2 of the guest stars appearing in the latest episode, which is why I asked on here.

I just found it, and it was The Office US I actually recognised his face from, although I realise he's been in quite a few more popular shows!

Can someone tell me the actors name playing the driving instructor?! Can't figure out where I've seen him before and it's really annoying me!
