Wife asks husband what he plans to do this weekend.  He says he was thinking of being like Jesus, hanging out with his buddy's all weekend, traveling around the country and talking to whoever would listen.

Husband then asks wife the same thing.  She says if that is the case then I will be like Mary. 

Like Mary? 

Yes you come home on Monday, I'll be pregnant and you never had a hand on me.  Husband stayed home.
