Funny maternity clothes need not necessarily be expensive, as you may get funny maternity t-shirts for less than $30! There are t-shirts that have inscriptions such as "not in a good mood", "baby on board", "I'm pregnant, what's your excuse?", " I'm making a human, what did you do today?", "Already smarter than Bush", "I just wanted a back rub" etc. There are funny clothes available for the father of the child too, with funny inscriptions such as "See how my boys swim,” "Man behind the belly"; "My pregnant wife scares me" etc.
