Sometimes I am extremely gullible. In case you needed proof, here is a recent conversation I had at a Shoppers Drugmart after I kept setting the alarms off every time I tried to go out door:

Roseanne: I'm really sorry; I promise I haven't stolen anything.

Cashier Guy: No problem. We'll just have to give you a quick blood test. [Reaches for his cash drawer.]

Roseanne: [In a very high-pitched voice] A blood test?!

Liam: [Whispering] I think he's joking.
