In "So You Can't Sleep", Joe McDoakes has gone days without sleeping. So, after you see him go through some sleepless nights, he consults with a quack doctor to finally get some sleep. Naturally, none of the solutions end up working and by the end Joe's given up.
The biggest problem with this film is that for once this McDoakes film isn't funny. None of the funny bits are funny and it was a serious letdown. While it's very watchable (as are all the McDoakes films), it is among the weaker entries in the series and is easy to skip. Plus, the old stock footage used at the end sure looked out of date.
