well...there's a reason why.
The first time I took both of them out Sparky was mid-air in her leap and Penelope just WAYLAID her. Imagine something from like ESPN Mega Hits Of Football and you're pretty close. Ever since then Penelope has had to work to get her paws on ol' Sparkster.
And it's HYSTERICAL how Sparky gets desperate as she makes the passes:
"here lady take it...NOW!....Shit...missed...okay..grr no mine bitch...ok lady...annnnnd NOW TAKE IT TAKE IT OH FUCK GET AWAY FROM ME DOG...shit shit here I come put your hand down get it get it getiiiiiit...!"
