Neil Patrick Harris reflects on this week’s “Glee” guest stint: “wildly grueling”

Neil Patrick Harris may be one of the hardest working men in showbiz but even he was a bit overwhelmed at the fast-paced work environment of the FOX smash Glee.

Broadway veteran Harris performed Dream On alongside series star Matthew Morrison and described the set as so “wildly grueling” that he forgot every one of his lines on his first day.

NPH said his favorite character on the show is hunky quarterback Finn Hudson who is played by Cory Monteith: “He’s dreamy. But also I think he represents a really great element of the viewership and what glee club can be because he’s a quintessential straight guy, kind of a bumble-y.”
