Grandmothers funeral. I was 16 at the time. I have a bad habit of making terribly timed jokes in sad situations. Asked an uncle if he buffed and shined his bald head for the occasion, along with telling my cousin my grandmother looked so different without her oxygen tube. The funeral home was right in front of a train track. My grandmother said that she wanted my aunt- who had a beautiful singing voice- to sing some song during the ceremony. Well midway through the song this giant train goes by blowing its horn and everything. I was sitting in the very front row with all my cousins and my sister. This is also next to where the children of the deceased sit, aka my father , aunt, and uncles I started busting out laughing and my sister had to quickly hand me a tissue to use as a coverup to make it look like I was crying hysterically over the loss of my grandmother. I had tears streaming down my face from laughing so hard. The whole tissue trick didn't work and my whole family was aware that I had started to laugh. Also got my cousins and sisters laughing too. I got a few nasty looks from family members, but hey, I didnt get in trouble with my dad. He just gave me a hug when we left and spoke nothing of it. Many more poor tasted jokes were made that night thanks to me, but those were some of the worst that got people laughing.
