Jessaleigh just pointed to a picture of her Uncle David (no motorcycle in the picture I might add) and said
"Dat vroom, vroom, vroom"*
Seriously she hasn't seen him since August... I guess sitting on his motorcycle made an impression (should we be worried?)
*the vr sound could also have been interpreted as a b or br. Jessaleigh' first syllable wasn't totally clear. Either way it is funny though
