The day my dad got arrested

In the hospital.

While donating blood.

There was a police officer bleeding out, and they had run out of the officer's blood type.

They can't order you to donate blood, but my dad was signed up to be available and when he got the call he jumped in his car and headed to the hospital.

The entrance was restricted to a round about traffic flow at the time of day my dad arrived, so he just made a (at that time of day) illegal left hand turn right into the lot.  A police officer on duty immediately fired up his siren and tried to pull him over.

My dad ignored him, parked and headed in.  So the officer chased him down and wrote him a ticket while my dad was strapped in giving blood directly to the dying police officer in the hospital.

Luckily dad thought it was funny, though the police lieutenant at the bed side also had a cow.
