Have you ever blame someone (like your pet) for your own farts, is that a sin?

I have blamed my hemster Fluffins last night when I had my pastor and his wife over for dinner. I told them that he has Irritable Bowel Syndrome... Thay didn't believe me becouse thay said that the noise from the fart was, and I quote Mr. my paster "deafening and way beyond anything that a small terrestrial rodent's aynis can produce". Am I going to heck now? I was jus so imbared and jus wasnt thinkin.
