"Love Is A Weapon of Choice" is the sixth episode of the second season of the HBO comedy series Flight of the Conchords.

Bret and Jemaine both fall for a woman whose missing dog has epilepsy, leading to a duel, a canine benefit and a couple of new tunes.

Jemaine and Bret are out for a jog when they are stopped by a woman (Kristen Wiig) who is searching for her epileptic terrier, Charlie.

Bret lets her know of the song he is writing, while Jemaine shows up 15 minutes early for his date, carrying flowers.

When Bret protests, the woman tells him that they can spend 15 minutes together another time, and Jemaine commences his date with her.

Jemaine also tells her of his plan to write a song for epileptic dogs, and, not to be outdone by Bret, to hold a fundraiser for them.

On a second date, Bret shows up wearing a pair of Jemaine's glasses, and tells the woman that he is creating an antidote for epilepsy.

Jemaine and Bret each try to outdo the other, and steal the mic back-and-forth before commencing a low-intensity physical altercation, which Murray breaks up.

They finally take the stage and perform their song, "Epileptic Dogs," accompanied by a slide presentation from Murray.

They break into the "remix" portion of the song and strobe lights begin to flash, which triggers seizures in all the epileptic dogs in attendance.

The song is a success, until the end when they perform a "remix" and the stage is lit up with flashing lights, causing the dogs to have epileptic seizures.
