One internet-famous example is between Japanese and Polish.
daisuki (大好き): I like [it, you, him…] a lot
daj suki: give [me] the bitches
Both are reasonably coherent sentences, if short. Without context, "I like you a lot" and "give me the bitches" are the most likely readings; suki means "bitches" as in "female dogs in heat" but also "overly domineering women" or "police vans".
