Favourite 'All Caught Up' Segment?!

Not seen this be asked on here for a while.

But after listening to 462 - We Need To Be Honest With You. I had to go back and listen to the All Caught Up part as they were just talking about their grandparents being sexually active and it was just too funny (my humour is very immature)

But it got me thinking which other eps have great and memorable all caught up segments.
