He comes up, his trousers fall down / risque de pantalons baissé

Tudor came up in conversation when two friends at the weekend told us that they thought smilingly of brother in law Tudor and the now famous trouser dropping incident. They were at Toulouse airport and waiting to go through the checking procedure.,The elderly man in front of them set the alarm bell ringing and was told to remove his belt. He did so and yes his trousers fell down. The poor man looked very embarrassed but the couple turned to each other and mouthed " is it Tudor?"
Having had the same experience which I related to the whole of TAG readership making artist Tudor famous in the area for more than his painting, he sent us this drawing. I think it should be used as a warning at the security points " Risque de pantalons baissé"
Amusingly in the list of posts " Tudor loses his pants" has its own label.
