The Bachelor Spreads His Alien Seed

Jesse Palmer, third-string Giants QB and this season's Bachelor, is now accused of completing a quarterback sneak into both finalist's reproductive systems. On this week's The Bachelor: After The Final Rose wrap-up show, winner Jessica and anxiety-attack victim Tara will dismiss rumors that they are both pregnant:
CHRIS: Well just like at the end of every season of The Bachelor, the rumor mill has been spinning.
JESSICA: I am having an alien's baby. [...]
CHRIS: Tara, are you pregnant?
TARA: I'm also pregnant with a two headed alien's baby, so...
CHRIS: You guys slept with the same alien.
TARA: Yeah, apparently so.
For the record, Palmer is Canadian (an alien) and, presumably has "two heads". But we're not up on our Canadian anatomy and can't confirm the latter presumption.
