Remember the "You know how I know you're gay?" gag from The 40-Year-Old Virgin? YouTubers Davey Wavey and Tyler Oakley take it to the next level.
While both weblebrities are down under visiting Sydney — did you see Davey discuss Tom Daley's hairy bum with Matthew Mitcham? — the polarizing gay duo has tag-teamed a silly new video, "25 Ways to Know You're Gay."
Do you want Darren Criss to sit on your face? Is the locker room the best part of your workout? Does your hair look like Tyler's? Yep, it might be time to come out.
Check out the naughty clip below.
