At this stage there probably isn't a person alive who hasn't seen Alec Baldwin's superb take on Donald Trump on Saturday Night Live - he's destined for Emmys. 

Last night Baldwin appeared with Conan O'Brien and revealed that people often come up top him on the street and impersonate Trump. Conan then mentioned that his staff think they can do a better version than him. Including a special guest.

They can't, obviously. But good craic nonetheless.
