Yes, i have ... and if i could spit the words out i would explain. The strange thing is it only happens around my children. Now, there's a real head scratcher ...
Many many times. It rarely if ever has anything to do with what's going on at the time, and it really confuses people. I get this recall of really laughable things, and it sometimes hits at inappropriate times too.
Yes. My Dad and I went to the bathroom at the mall onetime. When we went in, there was aguy in the stall blowning it up, had a lot of gas. My Dad and I looked at each other and silently laughed. Then it got super quiet. Then all of a sudden I made a huge fart noise with my mouth and my Dad and i laughed so hard, we couldn't even breath. Every once in awhile it will pop into my head and I will bust out laughing.
I guess I find fewer things funny now than in the past.
