Why wouldn't a practicing Catholic joke about the Sacraments and what would happen if they did?

[Stephen Colbert](https://en.wikipedia.org/wiki/Stephen_Colbert) is a high profile entertainer and an out-an-proud Roman Catholic. As reported by the Daily Beast , prior to taking on his new role as host of the The Late Show , he sat down in an interview with Father Thomas Rosica, "media attaché to the Holy See Press Office and CEO of Salt and Light Television based in Toronto, Canada", and amongst other things: > When Rosica asked him about making fun of the church, Colbert said he wouldn’t stop just because he has a bigger platform. “I mean I’ll still make jokes about the church, I’ll make jokes about anything… as long as you’re not being malicious, I don’t think you can leave anything off the table,” Colbert told Rosica, but **he would stop short of making jokes about the sacraments.** “It wouldn’t feel right for me, it wouldn’t feel good for me, **it wouldn’t be obeying my own conscience, I suppose, to make jokes about the sacraments**, or specifically the Eucharist… a nacho cheese Eucharist joke… not. I mean, the church is an important part of my life, I would be crazy if I didn’t make jokes about it.” The first part of this question is not about probing Colbert's (or anyone else's) conscience, but to ask: **are there any official teachings of the Catholic Church that would discourage Catholics from making jokes about the sacraments?** Colbert has been including in some of his more recent shows a segment called "Stephen Colbert's Midnight Confessions", which contains a series of running jokes using a mock confessional with Stephen in the role of penitent and the audience in the role of confessor. In show 149, which originally aired May 24th 2016, after Colbert's stint in the confessional, the segment featured a cartoonish representation of God putting himself behind a confessional screen and confessing his own sins to the audience. Putting aside any issue of whether Colbert has acted against his own conscience in this matter (by making jokes about the sacrament of Penance), **is there anything in this behaviour that would be transgressive of Church doctrine?** If so, would it just be a matter to be dealt with privately between Colbert (or any other practicing Catholic in the same position) and his priest at his next (real) confession? Or given the public nature of such an offense, would his priest or bishop have grounds to bring discipline in a more proactive manner (*eg*, by withholding the sacrament of the Eucharist)?
