Buck and Wanda Moosejaw and their Knives of Death. Need we say more? In Season 4, Episode 12, “Double Trouble in the Panhandle,” Booth (David Boreanaz) and Brennan (Emily Deschanel) try to solve a murder by going undercover as a Russian knife-throwing circus act — and it is amazing.

The costumes, the makeup, the heavy-duty accents — we love it all. But our favorite moment has to be when the two partners pretend to “get busy” in their trailer.

Here’s hoping they do it for real before Season 6 is over!
