Gift vouchers? Flowers? Some money in a card? It's never easy to know what to get your mates for their birthday when you've left it late.
Kimi Raikkonen might have raised the bar, however, when it comes to ringing in Ferrari team-mate Sebastian Vettel's special day.
The four-time world champion turned 30 on Monday, and a tongue-in-cheek video posted by one of the Scuderia's sponsors showing what lengths Raikkonen would go to to herald the big day.
As ever with the 'Iceman', it's not clear whether he means to be hilarious, but it happens all the same!
