Second Strip
-Gustav, von Eiffel, I presume? My name is Juri Gagarin. I heard you wanted a railroad built?
-There, all done. Opsie, where did I put my rocket ship? Seems I lay the rails right over it. I'd better beat it down so that the rail is nice and smooth.
-All done! That was quick!
-This is Gustav von Eiffel, compliments on the nice railroad, but you forgot your rocket ship on my drive. And by the way, have you seen my tower anywhere?

Third Strip
Gluff-Gluff the giant is building a bridge between the Earth and Mars. "There, the bridge is ready. Now, where did I put my bowling ball?"
"Oh, seems I put it under the bridge. I'd better pound it nice and smooth."
"There, not to bad if I say so myself!"
"Hi, I'm Juri Gagarin. Nice bridge you've built. By the way, have you seen the moon around?"

Fourth Strip
"I, Banging Beaver, put carpet in wig-wam. But where is my buffalo?"
"Oh, buffalo under carpet. I better pound it until it is nice and flat."
"Ugh, such noise!"
"Good day to you sir. My name is President Grant. Nice carpet you've put in. By the way, have you seen General Custer and his army around here?"
