Mum's hilarious response to teacher's email about adult-only holiday

Parents of young children know you need to take care when talking to them, in case what you say is misconstrued or taken out of context.

Now US cookbook author Jenny Mollen has found this out the hard way after a conversation with her young son prompted a frantic email from a worried school teacher.

Mollen, who is married to actor Jason Biggs, of the American Pie movie franchise fame, was holidaying without her children, Sid, 8, and Lazlo, 5, in Denmark's capital Copenhagen.

She had clearly told her children about some of the Danish delicacies.

That is when she received an email from a teacher, whose name is Karen.

"Dear Ms. Biggs, today in school your son shared with his classmates that you are in Copenhagen on an adult trip and have been eating (pardon my language) 'tonnes of penis'.

"While I hate to bother you on your vacation, I felt strongly that you should be aware and perhaps address the issue at your earliest convenience."

Showing she shares her husband's ribald sense of humour, Mollen fired off a response.

"Dear Karen, He's not lying. I have been eating tonnes of penis on this trip. Def gonna need to reign it in when I get home. Thank you so much for checking in on me. See you at drop off!" she wrote, before signing off, 'Jen'.

Mollen shared the exchange with her Instagram followers on both her personal and business accounts.

To clarify, she also shared a third photo – a snap of a menu from the restaurant Noma to illustrate her point.

Under the heading "Game and Forest Season 2022" is the item "reindeer penis ragout."

The post got a big response from her followers.

"The best thing I've read all month!!! Dead!" said one.

"Even got the reindeer pun in there with the 'reign it in'. This woman is genius," wrote another.

One questioned whether the teacher's name was really 'Karen' while another wrote, "Karen. The best."
