Watermelon

so apparently there is a rumor going around here that the watermelons imported from iran have been injected with HIV .. i'm not kidding .. now in addition to being ridiculous, the rumor is also impossible .. that is to say it can't be done .. i heard about it from my older brother .. and he heard about it from somebody at work .. the guy said he was buying some watermelons when another guy approached him and tried to convince him not to buy any because the iranians had injected them with HIV .. but the guy bought it anyway.
