[wagon train]

So, I pumped this morning and I forgot to release some of the air. I was bending down because I dropped my pen that I was writing with. All of a sudden the left cup came slightly loose and made a farting sound. My husband and I laughed so hard that we were in tears.   I had no idea the cups could do that!! 

Does anyone else's cups have a tendency to make the "fart" sound?

I'm really small so I have to stay completely still for the cups to stay on and if I move my arms at ALL they fart. And if I laugh at the fart it causes more farting. Last night my boyfriend and I had a laughing fart cycle for like ten minutes when I was using the BB... so yeah lol it happens
