Hammers or Hamburgers?

Becky: Hey did you tell Steve we saw him on his bike yesterday?
Travis: Yeah. He replied 'Pick up Sticks?'
Becky: Why pick up sticks?
Travis: No Hammblers.
Becky: Hammers or Hamburgers?
Travis: I don't know. Hamburgers. It's not funny, because they come walking by.
Becky: Huh?
Travis: shhhhh. I can't tell you because the secret people are here.
Becky: Did you plug in your phone?
Travis: Yeah it's hooked to the wall by my grandma.
