How I Met Your Mother
1x14 Zip, Zip, Zip
1x03 The Drowning Man [season finale]
Not Single-Handed's best episode -- the ending/whole second half felt like a letdown after the suspicions and tension built in the first, although the forest scene was stunning (as is all the cinematography in this series) -- but still strong. Fingers crossed for more.
(As noted previously, the series was original screened in Ireland as three two-parters in January 2007, January 2008 and April 2009, but ITV showed them as one series of three films.)
