Mishearing

I've always wanted dearly to go for a boat ride on this lake.

A boat ride? If you like, we can rent one of those hand-rowed boats out.

H-

Handjob... She mishears the first part of tekogibooto (rowboat) as tekoki (handjob).

Young miss?

If that's not to your liking, then perhaps...

... we could go with that swan instead?
