You know, after watching the first half of the I thought I'll give a rating of at least 9 or 9.5. But the episode sort of lost ground toward the end. I must say, though roughly silly, the pajama scenes and ones at the TV studio which runs silently in the background, were actually funny. Marshall's crappy fantasies flying like superman, and Barney's bed suit to impress women who may knock on his door in the middle of the night were silly but made me laugh.
I know this episode of HIMYM made not fall under the category of a sound comedy like 2 1/2 men or Gary Unmarried. But it was good enough and woth your 30 minutes of TV time.
