I have had a few funny ones
when my son was about 2 he asked me what was in that bag, and i said "poo" and he said, "how did winnie the pooh get in there!!!"
then a while later, we were in a public bathroom, and being a little boy, he wanted to see the poo, and he looked in the toilet before i could flush it, well i also had my period, and he saw it and screamed, 'oh my God Mommy you are bleeding to death in your poop!"
i wanted to stay in the bathroom forever!
The receptionist at my GI called and told me i needed to be screened for colon cancer, that everyone was at risk, i said, not me, she said, yes you are, just because you are young doesn't mean you can't get it. i said no, but since i dont have a colon im pretty sure i cant!
my funniest was at the dr recently, i went for an UTI, i told her i had a bag and all, and we talked for a minute, and she said, do you always wipe front to back? and i said, well with the bag that's not really necessary, and she said, ok i thought maybe they had left the rectum, and i said no it's gone. well she had me lay back so she could feel on my stomach, and she starts to press down and she says "now where did they put your rectum" i kind of looked at her funny, and she busted out laughing and says stoma! where did they put your stoma! she had obviously mispoken, but it was so funny!
And when i first got sick years ago, my dr said, i don't want to have to take your colon out, and i said, where will you put it? And he said, In the trash can. And i said, "well thats kind of gross I don't want it back after it's been in the trash!" and he said, we wouldnt put it back, and i said, "well won't i kind of die without it?" Now, keep in mind i was in the hospital on drugs!
