OMG
Dumb and Dumber To was in the library.
I checked it out.
Harry (Jeff Daniels) was looking for his abandoned daughter (Rachel Melvin) to see if she'd give him a kidney. After they find her, there's evidence to suggest that Lloyd (Jim Carrey) was really her father. The mother (Kathleen Turner) has reason to believe they might both be wrong. There are bad guys trying to kill them. I think I spoiled too much of the plot already.
Score: 10/10
