Not me, but a friend
Back in the days of student apathy, I lived in Halls (High Hall, Birmingham Uni) that was a short walk away from BBC Pebble Mill. At the time (mid 80s) there used to be a daytime show broadcast from there - Pebble Mill at One, if memory serves - that was shown on national BBC.

It got canned and on its last day, some of my mates went down to join the crowds outside seeing the show off. Using pillow-cases, they made amusing "T-shirts" with marker-penned slogans.

Unfortunately for the interviewer going through the crowds getting their thoughts on the closing of this national institution, he stopped right in front of my mates.

"So" he said on live TV, "why have you come here today ?"

"Show them your T shirt, Troy" said my mates, and interviewer-bloke was stupid enough to say "Yes, show us your T shirt".

The legend "Get your tits out Marianne" appeared on screen for a few brief seconds, Marianne being one of the presenters on the soon-to-be-defunct show.

The interviewer did a double take, said:

"I think he meant 'get your hit records out, Marianne'" and then said the immortal words "and now, back to the studio".

[EDIT]

This is actually on YouTube. It wasn't my mate Troy, but another mate called strangely enough Phil Collins:

You can see it here in the first minute:
