This episode was funny when we followed the guys and their struggle dealing with the flat tire problem. I really laughed out loud when Sheldon was singing and when the car was burning. Something that I seldom do when watching sit-coms.
The problem with this episode was the focus on the girls. They were not funny at all. They just tried do deal with petty problems and it wasn't in a funny way either. All the things Amy said that her mother had done and said to her almost made me want to punch her mother in the face.
Penny was, well, not giving any funny response to anything. She did not deliver the lines in a funny way and frankly few of them were funny.
Bernadette was almost invisible in this episode.
I really think they missed an opportunity not making the girls go out and try to get Amy a new look. First of all, the clothing try outs themselves could've been funny. Also, Amy could've got a sudden realization that "Damn, I'm hot!" and try to get a guy in a bar or something later as a way to deal with the breakup. Just a suggestion.
But instead they just sat at home and discussed problems. Funny, really funny... not.
The Bachelor part I give a 10/10. The Bachelorette (or whatever) part I give a 4/10.
Since I think that I at least laughed I don't want to meet in the middle and have (4+10)/2=7 out of ten. It deserved a little better than that so I give it more of a 7.5-8/10.
