They're probably so used to getting stopped on the street and roared at by millions of fans but some people just don't have a clue when it comes to music.
Kodaline were stopped and searched at the American border recently told 98FM's Big Breakfast that the strict guards weren't going to let them through either.
They didn't quite like the get up of the boys and weren't having it that the four lads were in a band.
Speaking on 98FM, they said: “The just didn’t believe we were musicians”
“[So] we sang Acapella at like four in the morning. The atmosphere changed immediately and they were like, oh wow, you guys are a band."
So after their song and dance at 4am, they were eventually let back into the US - their method is a bit like how you'd get into a lock-in in Dublin at the same time.

Also, Kodaline are playing a super cool and exclusive gig in Dublin on Friday and if you're one of their biggest fans, you really should be at it.
The secret gig is apart of the celebration of their third album which goes on sale at the end of the month.
As well as this, the band has also featured on Eoghan McDermott's CEOL 2018 album where they have re-worked their song, 'Follow Your Fire', into Irish (Ag Fadú d’Aidhme).
McDermott said about the album that:
“I’m so excited to announce the CEOL 2018 line-up. It’s one hell of a list and includes Kodaline, John Gibbons ft Soulé, Picture This, JP Cooper, Gavin James, The Coronas, Parson James, Wild Youth & loads more fantastic artists.
“We are especially honoured that after the untimely passing of Dolores O’Riordan, The Cranberries have very kindly gifted us the use of the original backing track for Linger, which has been recorded beautifully by Sibéal.
“The album has been in the making for over a year now, and the whole process has been phenomenal. In the last week of production, tracks were being recorded in Dublin, London, LA and New York, which is awesome. Mega excited to share it with everyone."
