Billy Eichner is upset that “How I Met Your Mother” is ending. Like, really, really upset.

Eichner, the genius behind the “Billy On the Street” videos, has spent the week mourning the conclusion of the hit TV series, which ends Monday after “just nine seasons.”

Earlier this week, Eichner uploaded a video of himself and HIMYM star Neil Patrick Harris berating passers-by on the streets of New York. And now, Eichner has teamed up with none other than Lindsay Lohan to continue his shiva shenanigans.

The pair filmed a spot in which each batter a car with a sledgehammer—a car covered in “Mother” imagery.

Alyson Hannigan is the only person I can relate to!” Billy shouts as he smashes a picture of the Jewish actress.

“What the f**k am I going to do on Mondays now?!” he yells later.

At the end, Billy and Lindsay allot a dollar value to each spot they damaged on the car, writing out a monster check for $500 to Orthodox actress Mayim Bialik. The reason? Spite.

Watch for yourself below.

J-Connection: Billy Eichner, Alyson Hannigan and Mayim Bialik are Jewish, as are HIMYM cast members Jason Segel and Jason Radnor. L’chaim!
