How can a tire hold cement without it ruining the yard?
(Bob returns to the Yard)
Wendy, Farmer Pickles and the Gang: (Singing) Bob the Builder, It's his birthday, Bob the Builder, Yes, it is! It's Bob's birthday, Can we sing it? It's Bob's birthday, Yes, we can!
(Bob pulling off a strong piece of wood)
Spud: Pull it harder, Bob.
Bob: (Straining) I'm...doing...my...best!
(The board cracks)
Bob: Whew, That was a tough one.
Spud: (Laughs) Can he fix it? (Laughs)
Bob: Yes, I can Spud. Haven't you got work to do?
Dizzy: Let's make Bob a concrete cake that he can keep forever.
Spud didn't know about Bob's Birthday.
