What is the most embarressing thing you have done in public to entertain your baby?

I was in Target yesterday with my 10-month old and he was getting hungry/crabby. So I started to make farting noises (which is always a big hit with him) and this woman peeks around the corner.....I think she thought I really was letting my bodily functions go to work. I'm not the type to get embarressed....but I did get a little red in the cheeks...!
