Michael Swan (APAC Convention, day 1) gave us some examples of stupid sentences that we teach in our classrooms:

“The oxen are treading on my feet” (Els bous em trepitgen els peus)

“Has your grandmother got any grandchildren?” “No, she ______” (La teva àvia té cap net? No, no en _____.)

“Those people have no teeth” (Aquella gent no té dents).
