Have you ever heard a ridiculous rumor about yourself? What was it.

I am a federal intelligence agent.  This is the best one of which I'm aware.

I have 12 children.  hahaha

  (((Pssst. The only reason he even got this job in the first place is due to Affirmative Action. Otherwise, he wouldn’t be working here.)))

 In reality, not only did my qualifications put me far ahead of expectations, I had also scored in the top five percentile of applicants in written tests for the position, regardless of their identities or my identity. I have never considered, sought, needed, nor used Affirmative Action.

When I was a senior in high school, I heard a rumor that I had slept with a particular girl who had graduated the year before.

I never acknowledged it as far as I can recall from 1977, but the ridiculous part is that it was true! That was when I lost my virginity.

Yes that I was dead. But I checked the Obits and I wasn't in it.

Once a couple of guys tried circulating a vicious rumor about me at the Rod and Gun tavern in Parksville. The rumor was that the hash I sold wasn't real hash -  it was that finger hash crap (made from leaf). But when the rumor reached the VIP section on the upper deck of the Rod and Gum I debunked it by forming a puff puff pas circle. Cheers!  

my grandmother told people I cheated on my husband for a bit

I don't think I really got any of that.
