What Episode?

I ask this 问题 as I think I have seen all of the Psych episodes, I just don't recognise two video clips from the fourth series' opening titles. The two I don't remember are Shawn jumping onto the 兜帽, 罩, 发动机罩 of a moving truck and Gus, wearing pyjamas and looking at a clothes rack. I would really like to know what episodes these clips are from as right now this dilema is annoying and confusing me!! To those who help a 粉丝 and a 支持 will be on your way. Thanks in advance!!
