Take, for example, Vitalii Sediuk aka the dude who dove under America Ferrera's dress at the How to Train Your Dragon 2 premiere in Cannes earlier this month.
If the name sounds familiar, that's because it's the same guy who buried his face in Leonardo DiCaprio's crotch at the Santa Barbara Film Festival, did the same thing to Bradley Cooper at the Golden Globes AND tried to kiss Will Smith at the Men in Black 3 premiere.
Now, Vitalii has added another act of ridiculousness to his resume. During the Maleficent premiere in Hollywood on Wednesday, he jumped over a barricade and somehow managed to get within striking distance of Brad Pitt.
So, what did he do? He punched him.
Yes, Brad's gorgeous face has now been kissed by a fist - and we're not happy about it, not at all. Judging by this photo, Brad's leading lady Angelina Jolie wasn't, either.
Video of the incident has not yet made its way onto the Internet, but if we had to guess, we'd say the first photo was taken pre-punch and the second one was almost definitely after.
According to TMZ, the repeat red carpet offender was detained by the LAPD and will be booked for misdemeanor battery.
The bigger issue is: How the hell does this guy keep getting so close to all of the celebs? Yeah, he was a reporter and maybe that worked the first few times. At this point, though, it's kind of embarrassing.
Seriously, guys - how many crotches have to be dive-bombed before you decide it might be time to start keeping a "keep out" list with this guy's name at the top?
