Doogie Does 'SNL' Tonight

If you’re a fan of Doogie Howser, M.D. and How I Met Your Mother star Neil Patrick Harris — and who isn’t, I ask? — you’re in luck because tonight he hosts the first new installment of Saturday Night Live in 2009. Also on the roster is wildly successful musical guest Taylor Swift.

Get a taste of what’s in store for Barney lovers everywhere by watching the following promo featuring Neil and SNL player Will Forte. Considering that the alter ego of Dr. Horrible is actually funny, this one just might be — wait for it — legendary, or at least consistently entertaining.

Saturday Night Live airs Saturdays on NBC at 11:30pm EST.
