ultrasound tech jokes?

Every time I go in for an ultrasound they comment on his head size and penis. Lol 
Like "woah he's got a big head... I'm sorry"...& "oh you said it was a boy, that's definitely true". Iv gotten a lot of ultrasounds recently,because of high fluid. Different tech every time. They all comment on those two things. Anyone else heard the same things over and over, or just funny comments?
