This weekend is extra special for Muscle Milk Pickett Racing drivers Klaus Graf and Lucas Luhr – both celebrate their birthday – Graf today and Luhr tomorrow.

The team celebrated the milestones at Canadian Tire Motorsport Park today after the autograph session with a commemorative cake for the two German stars.

Luhr went a step further to arrange a cream pie especially for his teammate to “wear”.

Little did he know, the team actually arranged two – Luhr also had some additional “lunch” all over his face shortly after.

Despite all the fun and games between the duo, both were thrilled with the performance of the HPD entry in this morning’s practice session.

Turning 43 today, Graf stopped the clocks at 1:07.404 (131.33 mph) in this morning’s first official practice session.

Michelin Alley caught up with the Graf to talk about the car’s performance and the birthday occasions after he had the chance to clean up the mess – having his cake and wearing it too.
